Good movie.
It's set in the near future when scientists screw up and put earth in a massive freeze that wipes out humans except for those that got on a powerful train.
Only the people in the back are treated like slaves and a burden, so they revolt to get to the front.
It's violent and based on a comic book... so it works for me.
Chris Evans is actually a good actor that works beyond playing super heroes, and comes across as a messed up leader here. The problem is, and I know they tried to hide it, is he looks like Captain America and able to break people.
But you can ignore it.
