I really enjoyed The Big Short overall, but I have two big problems with it: Christian Bale's performance / storyline and the damn wigs.
It's hard for me to understand how you can make a movie as good as this and not get the wigs right. Both Bale's and Carell's hair looks so fake it's ridiculous. Worse, it's distracting.
As for Bale's performance, it just strikes me as a series of gimmicks and mannerisms and not an actual character. The wig and the contact lenses didn't help.
