I dunno, I think season 2 was overall better, maybe because it wasn't interupted half way through by the writer's strike like season 1. Season 3 was the low point IMO.

Fair enough - you could argue both ways, really. But yeah, Season 3 was probably the worst - while I liked giving Chuck fighting abilities through the intersect, it just wasn't as good as earlier seasons.

I started watching Chuck last May, and I'm four episodes into season three right now. Good stuff.
