Better Than Canon: Does a great job of capturing what made the show great in the first place, while also making everything hilarious, lampshading (or even justifying) the less sensible parts, and occasionally managing to be deeper and more heartfelt.
The only exception so far, at least according to Shadowjack himselfnote Scroll down to "Quoted for truth.", is how episode 110 doesn't have quite the same impact with Meta!Usagi's current personality. Still, that's one instance out of 112 episodes and counting.
Growing the Beard: Episodes 7 through 13 can be considered this, as this is when the scripts got a little longer with more original content and humor, the alternate characterization kicked in and illustrations and screen caps began to show up.
Rescued from the Scrappy Heap: Quite a few followers in the threads end up coming around to characters they previous thought annoying, both from how Shadowjack handles them and seeing them again after so long with a fresh set of eyes.
