It's a decent movie. I liked it. But the real masterpiece is The Big Short. Though it wasn't given a wide enough release (smells fishy) it was the 2nd best movie I had seen for the entire year(#1 was Mad Max:Fury Road). So try Big Short! It's quite engaging and not boring at all. I'm a guy who found Skyfall to be bit boring. So you are really in for a ride if you get the intellectual stuff behind it.
The Big short 10/10
Margin Call 8/10
