I liked the two Star Trek movies by Abrams but it is impossible to compare the two Abrams' films to the originals.
I watched the TV Show "Fringe" done by Abrams, I never watched "Lost" so this was the first series I watched by him and I loved it, sadly only lasted 5 Seasons, I liked the idea of "Revolution" that just got cancelled. So I was familiar with the way his films / shows are.
I think a lot of what is going to come out is rumors. If they destroy the "Expanded Universe" which is what re-launched the franchise allowing for the prequels and now sequels then I am done.
Going back decades there are books, comics, video games, online video games that have advanced the franchise. If they get rid of that completely and ignore it then I think it is a spit in the face to all the fans that kept Star Wars alive after Jedi was released in 1983.
If the two ST movies Abrams did had been some other sci-fi instead, I still would’ve disliked them for countless reasons. I’ve been on record here voicing my dislike for what Abrams did to the franchise, especially as a fan since the ‘70s. To me, it is parody, plain and simple.
As for his other projects, I never watched “Fringe”, “Lost” lost me after the 2nd season (plus I already figured out early on the lead guy was likely imagining the entire thing at the moment of death). I only saw ads for “Revolution”, so never saw that, either.
At least in the case of Star Wars, the 7th film will be set after ROTJ, so he won’t be going back to rewrite the entire history or recasting the classic actors (no doubt if he pulled such a stunt, he’d never have been hired in the first place — it’s unfortunate the Trek saga wasn’t similarly protected from his wrecking ball).
