He invalidated Fred and Velma while (the "face" and the clue master, respectively) while often serving in Daphne's distressed damsel capacity....without any of their charm.
I don't think he's the worst character in the franchise (hey, remember Scooby Dum? I do, unfortunately) but his hatred is well deserved by fans of the original series. People who grew up with his iteration of the franchise are probably more forgiving about him. I more or less grew up with both and liked the original series much better, even with its trademark jankiness.
