I wasn't sure what to expect, since I don't really like fluffy romantic comedies all that much, but this one delivered.
Grant and Barrymore have great chemistry...if you like them, you should see this. Barrymore plays the slightly spacey, but sincere girl who's looking for a self-esteem boost after a bad relationship, next to Hugh Grant's corny but lovable aging rock-star 'has been' of the 80s pop group, called (what else), "Pop!".
He discovers her lyrical abilities and they team up to write a big hit for fatuous new teen pop idol (hysterically, yet frighteningly real portrayal here). Kristen Johnson (Third Rock from the Sun) delivers a great role as Barrymore's "Pop!" obsessed older sister. A nice 'feel-good' comedy.
