ive just never liked him
although i have to admit hes a better guy when with peyton (:
they bring out the best in each other

I have noticed some are not liking him but for me i have had issues with him sense last season and until he gives an logical explanation for his behavior i am not gonna like him i miss season 1-4 Lucas.

i hated him when he wasnt with peyton series 5 ... but now im liking him again - gradually and slowly!

its not that hes with peyton - its the fact he wasnt with peyton - mark messed up his character and i think people are just tryna let all that go and like him again!

I think that people are starting dislike him when he is an ass! E.g. when he cheated Brooke with Peyton [in season 1] or Lindsey with Pey [season 5]. I know that were just kisses but there were... ;/

Never noticed it! I think BL fans have hated him since the kiss or s4 and LP fans hated him in s5.

i don't like him since he got back with Peyton, but i like Peyton more now they are together.

Yeah, I agree with this statement. I'm one of them, but not because of Peyton, but because of his uncertainty and instability! As for me, I think he's weak
