Just a classic. I think it is enjoyable because of the multiple story lines going on at once so you never get bored. I would certainly recommend watching it but you do not have to start at Day 1 to understand - I started at Day 7 and was fine. Since then I have watch them all and some twice because as there is so much going on at once you forget what happened with every storyline. Although of course, I imagine it just depends on what type of TV show you like and although I am not normally into this type of stuff, I really enjoy it and own all seasons on DVD. However I would say my least favourite bit would be the movie as I was very disinterested with what was going on.
