Many people are thrilled of this movie so I was curious why. I went to the cinema, watched it and honestly I don't know what they are thrilled of :) For me it's just another sci-fi movie with nice legacy but we've already seen this in many different forms. The end is a little bit confusing because of time paradox but you just have to take it as it is. Don't think about it much or your head might explode :) If you like sci-fi go for it but do not expect any action in this movie, it's not about that. It's about legacy to mankind.
