Opinion & Informal
Art: 4/10 Stupid. I'm not sure if I would call any part of this art.
Animation: 4/10 Blatant instant-framing. Stupid rapidly flashing images. This will legit give someone an epileptic seizure.
Plot: 4/10 Stupid and pretty much just a random assortment of stupid clips they put together.
Development: 4/10 Pointless clips of stupid things strewn together.
Music: 5/10 Unfitting and honestly just makes the stupidity of everything about this more apparent.
Overall: 4/10 Despite being animated in 1975, this doesn't deserve any sympathy. This was stupid. Nothing was insightful. It seemed more like a test of animation or a display of skill, except there was no animation or skill to be found anywhere.
