I want to start off by fully admitting that I wasn't a major fan of the original PPG, though I did, and do, respect what it has done for the medium, and that I will be writing this review based solely on this episode, and this episode alone. That said, I'm sorry, but this isn't a good episode in the slightest. But, be wary: ahead there be spoilers.
When I first saw the previews before this, I noticed that every original character outside the original PPG characters looked as if they came out of Clarence. I had hoped this wouldn't be a case for all of them, but if this episode is proof of anything, that is the route they are going. While the colors are appealing, the designs for the new characters themselves are lazy, with one character model being almost completely ripped from another show. I'll explain more later.
The episode starts off at the Zen-aissance fair, a hippie festival. Why are they at a hippie festival? Never answered. Buttercup even asks this just before the episode's villain attacks. Now, I know the original PPG has had some really strange, and even stupid, villains - not just the recurring ones, even the one-off villains like the broccoli aliens and the disco nightmare. But this villain, Man-Boy, is terrible. He comes onto the scene declaring the festival too girly and tries to toughen it up with his manliness. It makes me think of the exact opposite of Femme Fatale, a villainess from the original series that was (very justifiably) HATED due to her butchering what it's like to be a feminist. This is literally the other extreme.
So, after he sends Buttercup into a rage, which causes her to defeat him, burn down the whole festival and give Bubbles a black eye (nice -_-) the girls take her to a guru they met at the festival, where he teaches her inner peace. Then, we get to watch the polar opposite of what Buttercup is supposed to be. Joke or not, this entire scene is painful to watch. Then, Man-Boy returns in a wooden tank driven by a polar bear followed by an army of t-bone steaks. I WISH I was kidding with that. Oh, and the polar bear? That's Ice Bear from We Bare Bears, just made to look scraggly. That is how lazy this art style is - they're full-on ripping off better shows of theirs.
After Buttercup tries and fails over and over, just to pad out the episode by an extra minute or so, she finally reaches inner peace and beats him by tossing him into a large tofu block. Then the episode ends. This episode is flawed. No doubt to that. It's not good. That is obvious. But, in the end...I might actually look at a few more episodes to give this show a solid chance. That said, this show is not off to a good start.
