Take This Waltz
Interesting in that it explores the notion that you can "cheat" on your significant other purely on an emotional level and the consequences of this. That said I had zero sympathy for Williams's character and some of the directorial decisions were.. odd to say the least. Also some of the dialogue didn't work - the whole "courage/bravery" line was pretty cringeworthy. It's a mixed bag; not as strong as Away From Her.
