Which series grabbed you from the start?

This thread is already turning out to be most interesting.

There are quite a few shows that I wasn't terribly interested in at the beginning, but which grabbed me later on as I kept watching. I think if a show can really grab you in its first episode, then it must have something special about it.

So what shows/series grabbed you from the start? Most of my examples are probably non-anime, but as far as anime goes, I think Bleach interested me straight away. Ironically I stopped watching after a few episodes though. I should probably go back and keep watching, because I felt that there was something refreshing and unique about Bleach.
