My friends saw Juno and really liked it.
The last movie I saw in a theater was Sweeney Todd, and while it wasn't a comedy, and was definitely bloody, it was a very good movie!
If you can find it, I highly recommend Into the Wild, which also isn't a comedy, and might be better left as a rental at home, maybe even after reading the book, but is a visually fabulous movie.
Ok... I wasn't really a help here.
