Abrams... well... I can't say I'm a fan. Nothing about his work sticks out to me and a lot of it I find just plain bad (Lost, the new Star Trek movies, etc.).
As for the new Star Trek, let me lay it out simple for you: Did you like the first one? If yes, then you'll love this one. It's better. If not, you'll hate this one as well, though maybe a little less. It's an improvement over the previous film, for what it's worth. Though it's no more a Star Trek movie than sticking a Snickers wrapper on an orange makes that orange a Snickers bar.
That being said, I'm actually OK with Abrams doing the new Star Wars movies, since the new Star Trek movies would work a lot better as Star Wars movies...
