The problem with Time Travel movies ,major spoilers

Rating: 7/10 (29 September 2012)

You cannot think about this movie seriously or you'll go nuts. As with all time travel movies , the paradox problem is always there of course not to mention the numerous plot holes which can never be explained. Like why was time travel illegal in the future ? and why was it not possible to dispose of bodies in the future,it's mentioned that people were tagged,in what way could someone be found if they were atomized in a vat of acid or similar way of disposal?.Or Why not just go back in time like Bruce Willis'character does and kill the person when they are a defenseless child and erase them from existence. But if you do that then they wouldn't have existed in the future you came from in the first place.
Too many things that are not theoretically possible.Like if you die in the past, your future self would never exist which basically makes the whole movie a huge plot hole which is always going to be the case involving time travel movies. I did like the first half of the movie but the second half bogged down way too much and the ending too abrupt and too many questions left unanswered/unexplained. 7/10
