When I saw the title
What Should Michael Bay Do?, my first thought was immediate...
Commit seppuku!
Yup, slit your belly to cleanse Hollywood of the dishonor you have brought upon cinema.
Bay is a hack, imo, who is only good at making trash and NOT HANDLING POPULAR FRANCHISES BELOVED BY FANS YOUNG AND OLD! He's Roger Corman but with less talent and a bigger budget. The only reason he got the job for Transformers and producing TMNT is because Paramount didn't want to lose a cash cow but were too fucking retarded to notice that he doesn't care about these properties at all. He's basically a pricy disinterested whore. He'll do the job but won't put too much of an effort so long as no one notices.
As for the idea of giving Bay anymore properties to butcher... or any work ever again for that matter, here is my short reply to that...
