Uhm, even if we only focus on those mistakes, those are fairly unforgivable. Most of it was tasteless low-brow humor that ripped any dignity Transformers had left from it's cold dead hands.
What about the "protagonists" of the movies? How could anyone forget that?
Starring Shia Labeouf in a movie about giantass robots kicking the crap out of everything as a PROTAGONIST? HELL NO

The characters ranged from annoying to completely unlikable and I can't recall a single 3 dimensional character through any of the ones I saw. This wouldn't be an issue if the movies would STOP FOCUSING ON THEM SO MUCH. I swear, the movies focus more on the obnoxious crappy characters and their butt-clenching pop culture references and sex jokes than the GIANT FREAKING ROBOTS FROM SPACE. (I only saw 2 of the movies, I will probably never watch the 3rd)

Also, the action scenes were a complete clustersmurf, it was impossible to follow really any action scene due to it being basically an orgy of metal and explosions, which makes the pretty solid CG and sound effects impossible to appreciate. I liked the designs on a lot of the bots, but again, action starts and good luck appreciating any good design. god so much more I hate... I'm just going to leave this here.
