Of all the things I could say, I think "trying too hard" is the most fitting and best delivers the message. This sort of, eh, "random" disjointed style of writing has been getting more popular for a number of years now (maybe because it requires low effort? Idk) and frankly I think it should have run it's course and died a while ago.
The animation (some of it at least) was pretty decent. I feel like there was a lot of wasted potential, I mean you can clearly animate, my question is why didn't you use your apparent skills to make something coherent?
Idunno, maybe I'm being too harsh, some of it was decent I guess. I'm guessing this accounts for a lot of practice, as the song says, everybody's got to learn.
