Did this movie even bother to explain what the fuck Optimus Prime was doing during the final battle? He just appears on the back of that dragon (which essentially does nothing) toward the end after everyone else spends 5 minutes getting crushed.
GOD, THAT MADE NO DAMN SENSE! Optimus makes a big deal about "I'LL OPEN A PATH" and logically you take that to mean he'll like clear the way for the good guys, maybe HE could have drawn the fire of the same generic Decepticon ships that we saw from the last film instead of the US Air Force's ships, but nope, he apparently flew around in circles to wait for the 3-headed dragon so he could land on it and fly valiantly in at the VERY LAST SECOND.
Even after watching this a couple of times, I' still not entirely sure what's happening, thanks to the 'fantastic' Transformer designs.
Megatron really needs to stop making his whole right arm a gun.

John Turturro's cameo return was nice. Stanley Tucci getting to be Merlin was OUTstanding, Anthony Hopkins was basically doing the "HARRRGGGGGHHHH" from Thor but for the entire movie, it has become apparent that Marky Mark is basically Michael Bay's self-insert lead (The hair being identical finally gave it away), and did anybody stay to the end of the credits to see if they pinned another stinger? I left after the bit with Gemma Chan as Human!Quintessa.
A more ambitious story probably would have had Optimus live out the Nemesis bit up to the final battle, and THEN he turns good again and sacrifices himself to finish off Quintessa, and from his crumbling body the Matrix of Leadership flies up and Bumblebee gets it, because no fucking way Hot Rod does in this film universe.
Speaking of Hot Rod, motherfuckin' Singularity bullets.
"I STOP THE TIME!" That was swell.
I wasn't just hearing things, right? That was Steve Buscemi as the other rotund Autobot?
Also, STARSCREAM'S HEAD HAS NO BUSINESS BEING INTACT. SAM SHOT THAT BIONIC COMMANDO CLAW INTO ONE OF HIS EYES, AND THEN STABBED THE OTHER EYE WITH A BOMB THAT BLEW HIS FUCKING HEAD APART! The only reason why his head should be intact is if HE's also subconsciously repairing himself like how Megatron's head wasn't completely dead, so then we can see Starscream return to backstab Megs one last time.
You know what would have kicked ass? Grimlock flying in on the dragon in his Autobot form, and then Grimlock turning back into a T-Rex and the dragon splitting back apart into 12 Autobot Knights. Grimlock should have said some shit and done more shit.
THAT FUCKING AMULET TURNS INTO THAT SWORD AND THEN RIGHT AFTER OPTIMUS SAYS HIS LINE, THE SWORD JUST VANISHES FROM CADE'S HANDS, LIKE DID THEY THINK WE WOULDN'T NOTICE THAT?!
