American Hustle is a good example of having really good actors who are completely miscast. Also, the story wasn't that interesting or at least should have been shorter. It's still pretty good, but it's probably the 4th best David O. Russell film at least.
It may be self-selecting, but everyone I know who has seen it has been amazed by Inside Llewellyn Davis including myself. It's not a crowd pleaser, one of the Coen Brothers serious films.
I saw Ender's Game last night at the Drafthouse and was really impressed. It's a weird, dark book that maybe only appeals to people who wanted to go the Air Force Academy as teenagers, but the film is remarkable well made.
I still need to see The Desolation of Smaug and Wolf of Wall Street. Going to see Her in about an hour.
