I just saw God Bless America; a movie I was told feels like a mix between He Was a Quiet Man and Falling Down. As I really enjoyed the latter two, I was hyped for this one too.
It delivered. I'm not sure Super earns the comparison, but the black humour was as harsh here as in the superhero-flick (which you'll see in the first five minutes). I won't spoil anything, so I'll just tell you all that you should watch it when you have the time to spare, although you should probably avoid it if you're an American patriot :]
