Love the interface. Love the simplicity. Love the graphics. Love the lack of [unnecessary] technical details and inclusion of details about the actual movie (rating, genre, summary, cover photo, etc).
Only thing I can think of to improve this is including a trailer on the download page. Yeah, IMDB is linked and that has trailers, but not quite as cool :) Also, related movies would be awesome.
So, yeah, it's pretty bad. We've also looked into http://www.traileraddict.com/trailerapi but there doesn't seem to be any reliable way to get only trailers from there (you often have DVD bonuses, making of, etc.) and their embed is pretty messy.
If you find a better solution, let us know!
