I have never played the computer game and haven't read the comic series yet, but after watching this movie, I will surely try to check both things out! It is true that this movie has many similarities to The Bourne series and that many films have the same concept and that's the reason why I don't give this movie a top rating.
But the story is well thought, there are many nice action elements, a lot of tension, some surprises and a little twist in the ending. The acting is well done, especially by the bad boys, but not outstanding. The movie is well directed and has some really good images and the dialogues are also well composed unlike many other films of the genre, you can really see that there has been some budget in this movie and that it is a high quality product. It is sad that the movie hasn't been in every country's cinemas though. I watched the about 180 minutes long version in one shot as it came out on DVD and I didn't find a single minute of boredom in the film what is quite exceptional.
In conclusion, this movie is more creative than many other similar movies with the same ideas and very entertaining so that I can't understand most of the negative critics. This movie is nothing revolutionary, but still one of the best of its kind.
