Sideways - DH and I thought it was great!
I adore that film! Makes you want to drink wine though...
Mary Poppins- um wow, the bf got it on his own because he thinks the "structure is amazing" (leave it to a playwright) and I cried 3 times. Haven't seen it since I was about 12 or so, and it made my weekend.
The Wrestler- Hmmm, it grew on me. Worth renting if you have a netflix-y thing.
Frost/Nixon- Love, love, love. Go watch it now. (IMHO)
