For me, the problem was the writing, the same stale, predictable writing. Watch any two episodes of Voyager or Enterprise with similar plots ie, a crew member gets kidnapped, crew mates risk all to save them, aliens take over the ship, crew has to claw their way back, etc and you'll see exactly what I mean. They're almost interchangeable. For me, it was like they were picking polts from the earlier series out of a hat and Voyagerising it, or something. Having someone like Abrams come in will do a lot for it, break it out of it's nice comfy, conservative shell. And I don't mean conservative in any kind of political sense or any of that BS, just take a look at Tom Paris. He was supposed to be the "Wild" "risk-takey" type! How family friendly was he?? I mean, I must be the devil compared to him!
You know what, if the 'core' fans get pissy, let 'em. It looks fantastic (so far) and it looks to give Trek that updated, edgy feel it's been lacking since TOS/TMP. If they wanna get their Cap'n Kirk panties in a twist over nit picky things like continuity or that Romulans aren't Bald, let 'em go for it. Most of us will be getting into it or trying to figure out how we dragged our wives and girlfriends to see it!
