IMDb is probably the best thing that ever happened to movie buffs. Now more than ever, you can get all the information you could possibly want about a movie, director, actor, producer, sound engineer etc. Big websites are always a hassle to maintain, and sometimes errors just happen. We are talking, of course, about the dreaded 404. But good design can make the experience of finding a broken or dead link enjoyable, and the people responsible for IMDb got the hang of this really well.
