Not really. Finn is an idiot but a likable idiot. Puck is a jerk, but he's funny and he clearly has a good heart. Something I've never seen from Kurt (love for one's father does not equate to being a good person) or Rachel, in fact, for a character who is redeemed by "correcting her mistakes," only ever seems to correct them when she benefits from doing so and it advances her own personal agenda. Its not like 'I was wrong, sorry.' Its more like 'Finn will like me better if I admit I was wrong, so I'll begrudgingly do that.' At least Quinn showed geniune remorse. I don't think I've ever seen that from Rachel.
Sue is a bully, but she's the antagonist of the show, so I can't really hold that against her.
Will geniunely cares about his students. He may let his personal life leak into his job, but everyone does and he always learns from it.
Ken Tanaka basically pressured and guilted Emma into that relationship by accusing her of being a home wrecker and he did so knowing that she did not love him, so its hard to hold her responsible for leading him on when he knew that she did not love him.
Finn is dumb, but that doesn't make him unlikable. In fact, he is, IMO, the most likable character on the show.
As for Artie, calling him a chauvinist seems like a stretch being as it just seemed to be a ridiculous tack on to the character to emphasize the whole women empowerment theme of the Madonna episode. He may be a chauvinist, but it was the result of bad writing so I don't hold it against him.
