my opinion, for what it's worth, is that Season 1 was adequate, Season 2 was barely watchable, Season 3 was excellent and Season 4 was the best (except for the last episode which was the greatest let down in the history of Star Trek).
I can understand not liking the Season 4 three-episode arcs though - they were very non Trek-like.
