Does neither he nor Michael Bay get it? It's not about "crazy action scenes" or "human issues", it's about the god damn Transformers. THAT'S THE TITLE OF THE SERIES.
The thing to keep in mind here: Michael Bay is good at
neither of these things.
I've seen the first Transformers movie he made. It's fucking awful. Most of it is just Some Unsympathetic Tool And His Magic Car, filled with really juvenile and ineffective comic relief (Michael Bay is some sort of toddler, I wager). The action scenes are kind of indistinct and bad, and he has no clue whatsoever how to maintain continuity in a scene (in one scene, there are a slew of giant robots who straight-up
disappear from the scene spontaneously and in a consequential manner, and at another point in the movie, it goes from middle of the day to middle of the night instantaneously via the magic of editing). The writing is bad, the action is very expensive-looking but not even that great, the acting is bad, everything's just bad.
It was too stupid to work on any sort of serious human level, the robots weren't good enough for them punching each other to be interesting, and there wasn't enough of it, so it didn't succeed as an action movie either, and the comedy was virtually entirely composed of sixth-grade-style pee/sex jokes, so it doesn't even work as a silly farce. And it's two and a half hours long. And the second one is said to be
worse.
tldr version: Michael Bay is an idiot toddler and doesn't know what he's doing and probably never will.
Oh, sidenote to Megan Fox: You did not display any legitimate acting ability in Transformers. Whether this was the fault of you or the director, it does not say anything good about you as an actress. You want to be taken seriously as an actress, yet the only thing you are known for is being (allegedly) attractive. Take your head out of your ass and actually start trying.
