It's a pretty fresh and honest look at an old story line. Gordon-Levitt had good comedy timing in 'Thrid Rock From the Sun" but he shows he can project a range of emotions and intensity. He manages to come a long way in under two hours - from pretty sophomoric 20 something to, well, a grown up. Deschanel also delivers a fresh and spot on performance, her character knowing exactly what she wants without seeming to be controlling or mean spirited and without being an air head.
The script was snappy and 'true' to my ear - not forced - with a few pretty funny lines, and some poignant ones.
