I watch it. I watch everything, I'm a TV junkie, lol.
I actually like Season 5 and 6. I mean, I tried going back and watching Season 4 a few weeks ago, and it was so strange. Lucas' hair was hilarious and everyone seemed kinda whiny. It was strange.
I like how they're adults now, the actors have always been adults so it fits more now. The characters have always seemed more mature than their age (ex: Brooke's fashion line, Haley's pregnancy, etc.)
