Bloody Disgusting has a review up at their site. It's blocked for me, so I can't link to it, but it's not too far out.
I really was hoping this would be a real home run for Abrams, but it's really not very good at all.
I'll stay away from spoiling it -- heck, I still have not finished watching it, mostly because I just don't care a whole lot (pretty sad, innit?) about finishing the ep, until it premieres. There's time to work out script issues are re-shoot scenes (barring a SAG strike). But wow. As it stands, it's worse than the Knight Rider backdoor pilot, by a lot.
