Clever and funny, catchy song too.
Okay, first, the positives. Great video, great song, great sense of humor. The little unmentioned cameos stuck in there randomly had me watching it over and over to try and see all of them.
The neutrals. The animation was good in most places, great in a few spots even. But there was a few spots that seemed somewhat... bland. Specifically when Godzilla picked up Optimus Prime. The lyrics were good enough to make this forgiveable, though.
And the bad. Well... it didn't have Mr.T? Uhm. Okay, I admit, I don't really have any complaints.
Hope to see more stuff in this vein from the creator! Very funny.
