I have no problem them ret-conning Primes revival as it was stupid and /almost/ anything would be better - esp if it leads to a new 2nd movie, or rebirth of "OG" cartoons.
2 human research team people find prime floating in space and want to save his body before he enters the suns gravity, they do so, but doing so got themselves infected with...hateful sun radiation? That then infects EVERYONE while they try and find a quintison (or, well the only one we know of from the movie, because hey that guy!) that HAS BEEN RUNNING FROM SHARKTICONS THE ENTIRE TIME - he comes to earth, rezzes prime because he made him? okay - meanwhile hotrod is emo, then hotrod gets infected, then prime has to get silver coated not to be infected, rips the matrix from hotrod, and then uses the matrix to cure EVERYONE - but depletes the matrix setting up the gotcha for the coming seasons. But bumblebee was remake into goldbug and no one ever cares about him again.
