In fact, he directed the episodes 4, 1, 2 and 3. For me, the first nail in the coffin was to dispense with all of the expanded universe, while some pruning would have been needed taking it all away was... well, the cynic in me says it's just to dispense with royalties and stuff; and I never liked the Yuuzhan Vong. The second nail was J.J. Abrams. I'm sorry, but somebody who disregards the internal consistency of a story is not somebody I can like at all, he wrecked all sense from Star Wars with his "let's teleport between planets, or to ships in Warp, and let's make a ship that can fire while in Warp", taking away all sense for an exploration fleet from Star Trek, while cloning iconic situations instead of making something barely original (minf you, Beyond looked like an extended episode to me, instead of a movie, which was kinda the idea with the first bunch of movies on ST). Then he went to Star Wars, and did the same thing: a Death Star firing through the hyperspace, disregarding how gravity fields would interact with hyperdrives with the "let's get out of hyper just after passing through the planetary shield", and all that... heck, SW7 was Harrison Ford dominating the screen the whole time, specially when he pulled the Obi Wan. And then, episode 8 and a pissing contest between directors. Now look at The Old Republic. And think that Disney decided to "pull the plug" on the old heroes, because new generation = new heroes. But instead of using something in the past, something in the Old Republic, they chose to go forward, crush what we had, and pull this... commercial mishmash. While The Old Republic keeps churning out cinematic "trailers" the same way Blizzard does with Overwatch. Frankly speaking, I'd have preferred some movie in one of the several Jedi Vs Sith wars, with civil war on the side. Plenty of things to show there, plenty of time, and less toes to step on.
Thats where i disagree with you. The expanded universe should have been nuked already 20 years ago. I have read alot of the novels and when i look back i wasted my time where i could have read superior sci fi novels. Most of the written stuff from the expanded universe is just Mary Sue Skaywalker, Antilles etc. The good novels can be counted on the fingers of the hand from a blind carpenter. The only reason nfor the existence of the Expanded Univers was, George Lucas got his share. And in regards to JJ Abrams. Abrams is a director that caters more for the younger audience, not for the old hardcore fans. Its his style in all his movies but noone today will watch something like the first Alien movie where for the first 45 mins nothing happens except for building up tension. And what Disney did is something what most of the fans begged for, since Return of the Jedi, maybe not your cup of tea but i liked it for shutting down my brain for 2 hours and looking at some cool spaceships etc. And for Star Trek i enjoyed the Abrams movies, in my opinion way better then the fuck up with Derp Space Nine and Voyager the already did. As said, my personal opinion from being a not hardcore fan of both universes.
I enjoyed Abrams's Trek, but disliked it as Trek. I liked Voyager, but not so much DS9. I like all of the new Star Wars stuff. The EU stuff getting cut up happened 10 years ago this year.
I preferred DS9 (well, S4 onwards) to the other treks. TNG spent too much time talking and philosophising and not enough time with the swooshing spaceships. (and pew-pew, and 'splosions.). While I admit, a peaceful future where everyone gets along is a nice dream, it was a mistake to include humans in that universe, since we are hardwired to not get along with each other outside of a certain sized group (tribalism is wired into us). I read maybe 10% of the EU, and of that, liked about half again. That said, I also played the old WEG rpg that Pablo Hidalgo worked on, and loved how Rebels and clone wars got to mine the EU stuff for the gems. I waited for voyager to "git gud" as they say, but it never happened. It's like the Dune books written after Frank Herbert died. The carcrash that only gets worse.
For me, Trek was about the philosophosizing and whatnots, so I liked that in TNG and Voyager had more of that than DS9 did, in my estimation. As for the EU and it being garbage, that's what I like about it having been gutted, they're taking the parts that didn't suck, polishing them up, and giving them to us, but different.
I know I'll never be considered to be a "true fan" of either - I've been in the fan-scenes of both for over 35 years, and my unwillingness to exalt them both to the status of "true faith" means I'll never be one of them. I don't believe in canon (in the fandom OR religious senses of the word) and I don't like ANY of the properties in their entirety, just the cool bits.
Star Trek TOS had the "rightest" ratio of "think, you audience" thanks to Spock, the action (and romance, and "screw the rules, we're cut off the Federation) thanks to Kirk, and the isolated "strange" episode. Truth be told, those episodes and movies demanded patience, something movies require less and less since 15 or so years ago (Internet, with twitter specially, favours short attention span...). Voyager... like a gum, became too long, too elongated, too many "we slowly go, and we keep interfering or getting interfered with local lifeforms", with really good chapters and lots of Borg (Mr. Munro being the king of the ST FPS games XD). DS9 simply... well, started as a Babylon 5 "copycat" (they got the ideas and some plots), and then the war started and we saw a completely new side of the Federation, a practical one. Kinda like how Enterprise has good episodes at the beginning, against the Xindi, and in the last season (with the isolators specially), with lots of filler episodes inbetween (and inside). In any case, the true gems in all of those are, for me, the ones about hard choices. Like Sisko said, "living with it". As for the SW Expanded universe, they certainly had a "Warhammer 40" smell to them, with so many disparities between the "level" of the protagonists and the writer's quality. As I said, I'm no fan of the Yuuzhan Vong, nor do I find the novel with the "small figthers piloted and fueled by the drained lifeforce of republicans", and Luke certainly plays like a Mary Sue... but there are ways to make a Mary Sue work, you know, and ways that don't (and are the easier ones). Shadows of the Empire was not bad, Kyle Katarn's games were a mess but had a good history, Thrawn's trilogy was so good (until the last part where the writer confessed he had grown too powerful and he had trouble designing how would he lose) Disney "ported" him to Rebels, and Daala's books weren't so bad either (specially since in the end, Pellaeon went from "2nd in command" in both of those to "leader of a non-specietist Empire", which was the triumph of the common guy). Sure Abrams gives the people what they want, but you can do that within the stablished frame of the saga, keeping the internal consistency, instead of not giving a damn of the rules stablished for all the (still) canon sources, that is lazyness pure and simple.
