This movie rules.
I saw this movie on 3 hours of sleep after 8 hours of school and a small nap. To say it was the perfect film to basically be in a hazy fever dream state to watch is an understatement. I really enjoyed this and what I think I enjoyed most is how much it is all nightmare logic that doesn't bother explaining a lot.
The main 'villain' also has an IMPOSSIBLE amount of charisma that when arrives on the scene you are locked into his every word.
The movie is a lot like the punk music that fuels it and its main characters. Aggressive, fast paced and very in the moment. A really really good modern siege movie with all the characters actually behaving like people would in that situation and succeeding or failing because of it. Good messy action too.
