This is the around the point where modern Sentai usually gets a recap episode to save budget, especially the ones longer than 49 episodes...but Go-Busters opted for a regular, although obviously cheap episode instead. That's kind of interesting.
It's pretty telling, too. Goseiger got retooled, but since it stuck roughly to the planned storyline, they could recap the show as a review of what Bladerun was doing. (There's a Japanese Sentai blogger who calls him "the real main character," and I kind of agree with that assessment.)
In Go-Busters, the plot goes through so many bizarre contortions that I'm not sure you could attempt to recap it in a way that was 100% logical. There's too many episodes that contradict other episodes, characterization is all over the place, and there's really no through-line for the show as a whole.
Seeing a modern "monster repaint" episode was pretty charming, though you can tell they haven't done these for awhile. The plot wasn't very creative and Mochiroid wasn't half so entertaining or well-handled as Eraseroid. There were some great composite shots in this episode, though.
