I don't quite consider LOST to be a JJ Abrams property - he didn't really have much to do with the majority of the show beyond "Executive Producer", that wonderful catch-all term for "Someone who's powerful enough to get money from us." So I don't hold the end of LOST against him. Cloverfield I refused to go see due to shakey cam and that the trailers gave me nausea (not normal for me), I didn't see Super 8 because it just didn't appeal to me. Looking over his IMDB page, there's a few things of his I've wanted to check out but just never did - Alias, Fringe, Person of Interest and Revolution. And I did enjoy Felicity, back when I thought Kerri Russel was drop dead gorgeous.
However, I've actively disliked his take on Star Trek since I saw the movie in the theatre. There was never a point where I like it, and I've been called a troll (not here, not on this issue) because I've actively criticized his take on Star Trek, which I see as essentially him making sub-par Star Wars movies. Which, ironically, is what makes me actually enthusiastic about his take on Star Wars.
Star Wars don't give a crap if you promote some Rebel from Barely Trained Recruit to Captain Of The Flagship in just a few days. Star Wars don't give a crap if you say "Use the Red Matter!" and leave it at that. Star Wars don't care if you gots the Magic Blood that resurrects peoples. Star Wars don't give a crap about using a sword to fight people probably armed with laser guns. Star Wars don't bat an eyeball at a laser that implodes planets. Star Wars don't care nothin' 'bout hiding a fleet of ships behind a rock. Star Wars don't know no geography, so you can be fightin' on Tattooine one minute, jump to hyperdrive then not be able to finish the expository dialogue before gettin' shot out of hyperspace outside Naboo. These are the things Star Wars says "Yeah, we did that - so what?". And we Star Wars fans go "Booya!" then laugh at the Star Trek fans who are having apocalyptic fits as our Star Trek gets this dumbed down idiot treatment.
So while I hate, loathe, dislike, gnash my teeth over his Star Trek crap, I'm going to go see his Star Wars in the Theatres because as Star Wars films, I've actually kind of liked his Star Trek stuff.
