Cool, I watch this from time to time. Very fun 80's soundtrack and messed me up as a kid with Prime going down. Always thought it was a pretty movie too and mostly well animated.
Yeah it was and is still fun, just wish they could go back and animate the story board scenes of the autobot city battle. We could then see Magnus and some bots take down devastator and meg vs prime would have some extra scenes.
Prime pwrishing.....well it was meant to be o be permanent, and the episode Dark Awakening really made it permanen but all the screaming kids and their parents made Hasbro pull a serious retcon to bring Op back
But yes his demise really screwed some kids up for a time.
