Instead of TRANS4MERS, I think they should just reboot it and give us the War on Cybertron.
Totally agree but wouldn't that be considered a "prequal"? Either way great idea.
It could be told as a "Prequel within a Sequel" kinda like Stephen King's THE DARK TOWER: WIZARD AND GLASS. They have covered some of the stuff in flashbacks, but I'd like to see a full-scale war film.
