Well, if anything, this particular thread is a prime example of how quickly a joke gets old on the internet. Honestly, Abrams is called director, and within ten minutes, 75% of the replies have something to do with lens flare? There were lots of other gripes to grab onto with his work, people. Something about dense, nearly unintelligible story-lines would have worked just fine. Or something about a keyboard solo...
OT: I'm a casual Star Wars fan at best, and an even more passive observer of Star Trek. I've seen all the movies in the first canon, and all the 'Original Series' films in the latter, as well as a large chunk of Abrams work, so I can see where the good and the bad in his direction could lie. But I also rather liked the 2009 Star Trek, so I'd be interested to see where he goes with this.
However, given that he is directing the Star Trek reboots, I'm not entirely sure just how accurate this info is. In Hollywood, 'word on the street' is wrong just as often as it's right. I'll wait and see what happens before I pass any judgement.
Although I will say that I agree with an earlier sentiment stating that Joss Whedon should have directed. I think that would have been really cool.
