Sam didn't really become a character for me until I'd seen the series all the way through.

I was initially meh about him, though he did grow on me. I like him, and I think throughout the course of the show that never really changed. (Unlike my feelings for Starbuck, Lee, or Gaius - those I flip flopped on a lot.)

I'm much too lazy to advertise too :P It's why I'm a terrible LJ correspondent - I get so lazy and then don't respond to comments until days later.
