Baby Mama was a nice surprise, yeah.
500 Days Of Summer was very good, I recommend that warmly. Adventureland I haven't seen.
Hmm, of the newer that I can think of, 27 Dresses was OK. Also I Could Never Be Your Woman and The Rebound. Also Genova and Personal Effects if you like the drama, pretty heavy stuff.
Be sure to skip New York, I Love You though, very boring and bad. I expected much.
