TL:DR
A music video that you should probably not watch, but the song is quite good.
Ok, on to the real review.
It's quite a bad music video that I have no real idea why it exists. It would be better as just a song, which it redeems itself with. Literally everything about the music video is terrible. Anime characters as big as a bridge? Ok? Random dance moves, Check.
It's just not a great thing to watch. Very cringe worthy. But the song is one of my favourites to date. All I an say that just listen to the song instead of watching the video. The video ruins everything. I can't stress enough about it.
The only reason I gave a 3 for art was that the animation quality wasn't that bad.
