Iron Sky. A lot of young chavs grabbed their beers and left the theater. Apart from a couple of minutes you can mostly see in the trailer that movie is indeed pretty shitty. The sequel is even worse. It was pretty overhyped and I suspect it hasn't aged well.
I wasn't one of those chavs walking out. I knew perfectly well what I was walking into. It's pretty boring, though. It should be a short film of 45m max.
