definitely

I didn't like him so much in this season.

I love Lucas in so many seasons... but I was honestly kind of glad he was leaving the show after season 6. I think he brought down the show in season 6 and made things soooo boring. He had a few good scenes throughout the season (and one or two really good ones), but overall I felt like CMM's acting ability plummeted that season. It was really painful to watch just how lifeless he seemed (with obviously the exception of a few scenes here and there).

& Season 2

Such an ass.

He changed this season. Don't get me wrong a lot for the better, but a lot for worse.

I barely remember any good and memorable Lucas scenes from season 6...his character got sooo boring, almost pointless IMO / =
(Well, except for his relationship with Peyton, he didn't do much. Being an unsuccessful author barely counts...)

his hair was soo awful xD
