great movie could've used different ending

Rating: 8/10 (21 June 2007)

WOW! great movie, fine writing. after the first 30 minutes you THINK you're watching a detective or CSI stylish movie with federal agents simply trying to find a terrorist. after that, for about 20 minutes you THINK it's becoming some kind of 'Enemy of the State' rip-off with federal agents using satellites in combination with some high-tech software to the crazy extend of generating a live video feed of a few days ago. i was thinking 'wow, enemy of the state was crazy with their sat tech, but this is just preposterous. then, after that we finally get to know what's going on. and at that point, it doesn't even hint to reality (although it tries to proof the hypothetical possibility of this actually happening in reality, LOL) but it's OK that it's a bit unrealistic from there on, it's still great writing and keeps you curious.
now for the end of the movie, you actually get the feeling that whatever Denzel is trying to do to fix the past, he just can't and everything will be as it was. all the links from the beginning to the end of the movie (ambulance in shed, blooded clothes, everything in the woman's house) seem to link so you really start to think that Denzel cannot change the past as he is already part of it. or will the writers surprise us? eventually they do... but for me, they could've made an alternative ending that actually let everything happen like it would've.
apart from that, great movie!
