It was decent. The action sequences were definitely a bit choppy, especially the first one. Also, there were a few times when I had to go "Is that even physically possible?" and the ending left a few loose ends still left, so I was sort of disappointed with that.
If you don't pay attention, you will hate this movie. It moves fairly quickly, so once you miss something, it's gone and you will be lost. So pay attention. The story is actually pretty good and actually feels down to earth, which is more than I can say about quite a few sci-fi movies.
For the record, I went into this movie not expecting much more than average, and I was slightly surprised. If you go in expecting the next academy award winner, you will completely despise it. It is no Dark Knight, so don't expect it to be. There's not much there artistically, so, if you don't like a movie simply trying to be entertaining for the sake of being entertaining, then you won't like this one. All in all, it was a good watch, not entirely worth the price for a new movie, so I suggest waiting until it comes to the cheaper theaters (if you have one near by).
As another note (and I'll probably get some heat for this) I actually enjoy Vin Diesel as an actor. This is not his best performance, but it's certainly not his worst (even though I still moderately enjoyed Chronicles of Riddick, I admit it was pretty bad and to this day I still don't know why I like it.) I think Diesel is good at what he does, although he really hasn't been in anything that really blows me away, even my favorite Diesel film (Pitch Black) wasn't completely stunning, but it was really good. With that in mind, this is a Vin Diesel movie, so, if you're not like me and you don't like Diesel, you will not like this movie and should just steer clear of it.
