Truth is I wasn't impressed by the trailer, like it felt like a typical action movie, but then I watched the movie and found it interesting. The movie starts off with a short but thrilling rescue operation which definitely pulled me in to watch more. Then the second part shows the revival and what the Nanites can do and being a science geek that was quite extravagant and made me want to watch more. I am not an extremely big fan of action movies, but Sci-fi Fight sequences in this movie felt more real than any one person fighting 20 people type of fights. I am watching through this movie for an hour which I never noticed passed and the big twist comes in making me sit at the edge of the seat to find out whats going to happen next. This movie is definitely a roller-coaster ride that exactly when you think is over takes you on a second round. Maybe I am being biased because it is really good to see a Sci-fi movie that is not a Marvel/DC Superhero, Star Wars,Star Trek and Sequels. In that aspect this movie was a treat for real Sci-fi fans who just want to watch something fresh, even though it isn't and story feels reused.
