Season 1 :) watching the early dynamics and chemistry of O'Neill, Jackson, Teal'c, Carter, Hammond and Fraiser play out was gold. I was only a little kid at the time when I saw the show, but I swear I learnt the craft of acting from these pros, they left such an impression on me. Richard Dean Anderson and what I could only assume now was genius ad libbing made me laugh so much. He just knew how to be relaxed and wholeheartedly truthful. Amanda Tapping is a director now too, which is just so cool.
