Sort of disappointing.
I've been an Egoraptor fan since the beginning. In his movies, I love the animation style, the flow, the jokes, the voice acting... everything. This one had a larger build up than most of his movies. I have been waiting for this flash from the moment Girlchan in Paradise Ep 2 was released, hoping for an epic, hilarious romp through the nostalgia of transformers.
Unfortunately, there's not much payoff.
It's funny, sure, and the animation is great (as always), but there wasn't anything all that original about it. It was shorter than I would have liked, there weren't any jokes that stood out, and it's just generally below Egoraptor's standards.
I hate that many will blindly give this a 10 (based on the two flash legends Egoraptor and HappyHarry being attached) and just assume that it's great without really thinking about it. I would consider this the low point in my Egoraptor fandom, and will just wait to be wowed by the next one.
