I've been told this anime is unreviewable.
Challenge accepted.

Emperor High School is the worst school in Japan, a place no teacher would survive, not even criminals.
Hoping to bring order is Ganpachi who paints an intimidating figure as he swiftly puts Hinako, the gang leader, in her place after revealing her love of Lucky Kitty Gym Pants.
It's revealed that Ganpachi is a genetic experiment spliced between a human and a cockroach and he escaped from the very lab that created him so the second half is just one big goofy battle.
This is one of the rare occasions where the British also have a dub as well as America, the British one is sillier but the American dub paints Ganpachi better.
I don't believe it's as unreviewable as people think as Ultimate Teacher's comedy really relies on what your taste in comedy is, in this instance it's screwball comedy with a hint of random as stereotypes are dotted about the film which have no business being there in the first place.
It has a good first half but the second half, the best jokes have already been used up so it finishes weak.
Final Verdict: For an 80s era anime Ultimate Teacher is a rare treat to show on any anime night but it's comedy has a short lifespan so I'm grateful it's only 55 minutes long.
