So, in summary:
"I love this game. It was a blast and was hilarious. I don't regret buying it on release day at $45-60"
"This game sucks. It's short. Seriously, I wouldn't spend $20 on it."
"There's replay value and I feel I've gotten my money's worth."
"You're not part of my cool club 'cause you spent over $20 on a game."
"I don't mind spending over $20 to support small developers who put out original content."
"Dude, everything they've done sucks."
"No it doesn't."
"Dude, this game's not nearly as good as Devil May Cry."
"Uhhmm...ya, it's not supposed to be. It's kind of campy and tongue-in-cheek. That's the point."
"You have no taste. Seriously people, don't buy this game!"
"YOU have no taste. Seriously people, check it out. It's a great game!"

Did I miss anything? So, I think it's completely obvious what anyone who's still on the fence should do
