I totally agree with this commentary. Bay was left to run amok, film explosions, chase scenes, and other non plot related stuff until the money ran out. It was an exorcise in excess.
I genuinely feel bad for all the crew that toiled for countless hours over this to make this film look amazing. However, without anything resembling a plot it's just 3 hours of robot fellatio.
The fact that someone worked for hours on end to create Devastator's testicles, then the fact that they couldn't even get the joke right "I am under the enemy scrotum". It's just sad.
I think I despised the mother almost as much as the Chris Tucker-bots.
If they would have stuck with just one idea the film may have worked. Instead, it feels like the script was written by two guys pulling ideas out of a hat at random and then filming in that order.
On a side note, over here at Drexel University they filmed some of the college sequences on campus. I saw Bumblebee but sadly, no Megan Fox.
