**spoilers!**
I was disappointed at first that our main character was a brainwashed bad guy. But this is a redemption story and after the first bit of the movie I was engaged. I would have chosen to add some and take some away with this movie but I would say it holds up as a sequel with no big name actors. Once the main character meets up with the main group of people it really is interesting and suspenseful. The ending is great and I'm already looking forward to the next one.
