It's not that we're balking at the CGI, it's the instinctual reaction that the style of animation just makes everything look OFF because they're trying too hard to make them look realistic. http://tvtropes.org/pmwiki/pmwiki.php/Main/UncannyValley

Honestly, I wish they made it look as cartoony as the comics do. Never read them before, but the way they made it to UV-ish makes me afraid that it'll be a flop.
