This was the movie that I did not plan to watch last Saturday. Anyway, in the future, the prisoners will be sent to outer space as there would have less chance of escaping and repeating the crime. Then, they were put in capsules and put to sleep. However, to start the conflict going, the unexpected happened when the prisoners took over the space prison and one of the hostages was the president's daughter herself. In order to free her, a hero was sent - not only was he strong but he was also able to handle all kinds of tools and machines. And towards the end, only two people survived and you could guess who they were by now.
All in all, the movie was entertaining and considering the genre, the violence level was still tolerable. However, I must go watch "The Avengers" after this.
