Great
The animation and voice acting are amazing as usual for Leo & Satan, but it wasn't quite as funny as the other three. Still a joy to watch, and pedo-guy is still the most hilariously disturbing thing ever.
As for the people saying you should put this series to rest since this one wasn't as funny are CRAZY. 3 out of the 4 Leo & Satan's were fucking amazing, with this one being pretty great. That doesn't equal series death at ALL. That means try again. Many a great series has had a few shitty episodes, and I wouldn't even call this one shitty. This one didn't live up to people's expectations, so they're going to talk it down, but their expectations were probably a bit unrealistic to begin with. I look forward to the next L&S.
