This was EPIC!
Oh god diddles jesus.
Considering how much potential there is in the Simpsons universe, the lack of pretty much anything is a swing and a miss here. It's not bad animation, it's not bad voice acting. It's just too short. For how expansive and with how many opportunities for jokes there is to land when parodying an already existing universe, this is just not enough.
Had it been part of a mashup of parodies, the length would be fine, but standing alone, this is just too short.
