One of my all-time favorites is
The Wedding Singer with Drew Barrymore and Adam Sandler. Partly the 1980's soundtrack, partly a lot of very funny moments, and just two very likeable characters, and a very likeable supporting cast as well. I kind of fall in love with Drew Barrymore a little every time I watch her in this movie, and it's one I can't resist watching again every time it's on.
