I like them as simple amusement instead of serious entertainment. You can do much better if you're looking for smarter, better written and better animated cartoons, but if you prepare yourself for a wacky internet meme-spawning cartoon they're pretty good.
It could potentially be neat if they were redone and improved drastically. Maybe a comedy Mario show that doesn't suck on Adult Swim or something? lol, just a thought.
Well, I kinda hate them since they are a bit insulting. But, for something to laugh at and make fun of, I think they are pretty good (ugh, the Zelda cartoon introduced "Excuuuuuse me princess." UGH!).
I liked them both. But I did enjoy watching the Mario one better. The Zelda one was lacking, but then again there wasn't much to go off of, so you really can't blame them for making it so bad.
