I've seen most of the episodes through the end of season 6, so I'm a fan of the show. I noticed that you can get the whole Season 1-7 set for $248 at Amazon, so that's something I'd really like to have.
I haven't seen Angel yet though, so I suppose that's something else I'm going to be wanting, especially with some crossover between them.
You know, I saw one or two episodes when it originally came out (plus the movie) and I thought it was silly. Then, I kept hearing so much about it that I decided to catch it from the beginning on FX. Now, I think it's one of the best TV shows I've ever seen. Better late than never, right?
