My daughter had a 19th birthday last weekend and wanted to go see a movie with the family. In a rare occurance, her brother (14) agreed, immediately, to go see Duplicity. Daughter drawn by Julia Roberts, son drawn by Clive Owens and I just went along to pay for the popcorn.
I really enjoyed the movie, mainly because I like Paul Giamatti is everything (except, ironically, Sideways -- but I didn't like anything in that movie) and the double and triple crossing was amusing.
Both kids hated it.
If you're going to see a luminous Julia Roberts, stay home. If you like triple crossing twists (and trysts) and turns, it's amusing, but you don't need to see it on the big screen.
