It's fun in a campy, over-the-top way, but it also touches upon deeper concepts and themes from time to time, even if all Transformers fiction is meant to sell toys. It can be bizarre. Time travel. Rumble turning into a tree, or Rumble collecting bird poop. Dinobot Island. Galvatron going completely insane. Quintesson wizards. Wheelie having a crush on Papika. Shadow parasites. Rhinox farting. Transmutate. Robot heaven. Blitzwing's multiple personalities. Starscream's clones. Stupid drones. Hey, those last two kind of rhyme! Additionally, all of those things I just mentioned don't belong in this narrow category. They're all strange, but they're also quite broad, and Transformers as a brand can include any of those things and much more. Finally, the idea of thinking, feeling, alien robots who are life as we don't know it, but who also struggle to survive and make sense of an often dangerous universe resonates with me, and the toys can be cool, too.
