After viewing it, I'd say it was lacking actual show quality in both animation and acting, but not by a monstrous degree. The dialogue was a bit too cheesy for me, as was the moral. This is, however, better than being out of character or having a contrary moral, as these were not a problem. Some references are good, but I feel this was way overdone. The part where Rainbow Dash [SPOILER ALERT] enters the Powerpuff Girls world was almost facepalm worthy. The soundtrack was very well designed, and probably the most enjoyable part. All-in-all, I give this 3/5 stars, for good music, decent animation and voice acting, and lots of effort.

I was expecting a cute, heartwarming, slice of life adventure, developed by the fandom's most creative minds…what I got instead was 30 minutes of horrible writing and crappy "maymay" references.

The horrible thing is people are going to defend this on the basis that "it's a fan episode".
