Forget about the plot holes ...

... and you might be able to enjoy this. Also if you hate the Cruiser (Tom Cruise that is), you might have a difficult time with the movie, too. Many people criticized his acting at the beginning of the movie, but I thought it was good and it also had Dakota Fanning, to earth it/make it believable.
The movie starts slow, but gets in gear fast and stays fast paced throughout ... well not entirely, because when a certain character comes into play late in the movie, it all slows down. You could say it comes to a halt. A full stop so to speak ... and although the following segment is very good, if looked upon as a separate piece, it just feels weird and not right in the movie (for pacing reasons alone).
The end won't satisfy many people too ... but it's difficult to find an ending that will satisfy everybody I guess ... btw. I didn't like it as well, but you have to make up your own mind. All in all a nice sci-fi pic then and sometimes even really scary and also real (emotions of the people) ...
