Eh. He's alright. (In the sense that he's alright to have around as a character, because as a person, he's just an a**.)
I don't love his voice, but I don't hate it. I appreciate his presence bringing drama up for Klaine, although there are definitely a lot of things I think could have been better about how they wrote his stories, and I also think there are a lot of more interesting places they could have gone with Klaine. Aside from the monkey wrenches he throws into things, I don't find his character particularly entertaining, but I also don't find him particularly annoying. He's just sort of... there.
So yeah. I don't really have a strong opinion, positive or negative, on the character.
Woah, its nice to know that even though I could care less, you all care so much. It's a shame that you all wasted your time on this, when its obvious that I'm the best thing thats ever happened to Dalton.
