Transformers
Have an actual fan write the script, no big name actors, TF is not about humans. Hell, make it in Cybertron.
Use the Prime 1/XM G1 designs, It's ****ing possible to make characters not look like excrement like what Bay did. So much potential, but we keep getting abominations that make absolutely no sense, can't tell what the **** is happening on screen, Shockwave looks like a hentai monster and Devastator is an over sized pug.
Burn it, Remake the hell out of them.
