It's blasphemy, I know, but if I could change anything in G1, it would be making the four MILLION years something more reasonable, like maybe four thousand... Or four hundred. I actually like how the Netflix shows did this with a time portal. Obviously robots don't age like humans, but the idea that in four MILLION years, the status quo on Cybertron barely changed at all is just silly. I think the comics introduced the idea of a great shutdown, which makes some sense, but still. Shockwave accomplished next to NOTHING but he's still in charge?! And the bots aboard the ark didn't dissolve into molecules in the volcano in all that time?! Also, if anyone isn't reading/listening to the transformersreanimated.com podcast, they're doing G1 season 2.5 and it's MIRACULOUS!
