Without a doubt Transformers: The Movie. Oh man if only they had had dvd's back then I would still have my first copy of it(I have it on dvd now, along with the whole television series), but I wore out the tape watching it and rewinding it. A lot. Shit I must have watched it over 100 times per year for several years(a conservative estimate considering I recall watching it 2-3 times per day and was probably 12 before I stopped watching it atleast 3 times per week). Also I was about 12 or 13 before I could get through it without crying when Prime died. I still hate hot rod(doesn't deserve caps) for murdering Optimus! what kind of justice is that? hot rod became rodimus prime and took Optimus Prime's place? The TV series went to hell because the new leader of the Autobots was queer(see "flaming decals", and "so bad that they needed to invent a bullshit story to allow the return of Optimus Prime in a futile attempt to save the franchise"😉. Grrrrr. Sorry everyone I am very passionate about this one topic(obviously). T2: Judgment Day is a distant(see "intergalactic"😉 second favorite.
