Well ... that was a marathon! In short, I did enjoy it.
• Plenty of destruction
• Ample amount of human deaths
• My Little Pony appearance
• The robots we know as Cybertronians, are made out of "Transformium"
• Ratchet dies
• Leadfoot dies
• Brains lives
• Galvatron IS Megatron reborn
• Drift is essentially a triple changer (car, robot, helicopter)
• The Dinbots are Lockdown's prisoners
• Transformers are not born, they were built by "The Creators"
Cade Yeager (Mark Wahlberg) - I thought he did a great job, such a pleasant change from Shia LaBeouf. Though playing a inventor doesn't seem like his sort of character, given that said inventor then gets drawn into battles between giant alien robots and manages to hold his own against them.
Tessa Yeager (Nicola Peltz) - Oh so conflicting ... at the start I was very impressed with her, she was coming across as a strong female lead ... but then once the explosions start she switches into damsel in distress, before alternating back and forth between the two. You can't be strong AND weak. One big miss for me with her was her bright pink lipstick which made her look (more so) like eye candy.
Shane Dyson (Jack Reynor) - Pointless. Only use for him was to add dialogue between himself and Cade. Didn't really do anything otherwise.
Joshua Joyce (Stanley Tucci) - Good guy? Bad guy? Bumbling idiot? If anything he's filling the role of Agent Simmons. He starts off as a collaborator with Harold Attinger and vivisector of Transformers (hence bad guy, and also intelligent), but then turns into a bumbling idiot and by the end of it is offering Cade a job.
Harold Attinger (Kelsey Grammer) - Not a stand out performance from him but he did a good job playing the head CIA agent, business partner to Joshua Joyce and go-between between Joyce and Lockdown. At least his character didn't change.
James Savoy (Titus Welliver) - Standard second in command bad guy. Hates Transformers because his sister died in the battle of Chicago.
Su Yueming (Bingbing Li) - Not a major role, but as the Chinese business partner of Joyce she did a superb job. Got her own little kick arse moment and may in fact be the person responsible for Joyce becoming a bumbling idiot (she is quite attractive)
Optimus Prime - Same ol Optimus, though unlike other Optimus', this one is sick of the humans crap. With good reason, they've turned on them and are now hunting them down. It's revealed he is also a Knight of Cybertron (he can also fly now)
Bumblebee - Takes a bit of a back seat here as the story centres more on Optimus Prime. Bumblebee still uses radio to talk and to me, has mentally regressed and is now a petulant teenager (a point that Optimus Prime states that he and Cade both share).
Hound - John Goodman did a fantastic job of Hound. A number of great lines. Truly enjoyed the Hound character.
Drift - Samurai face looks stupid. Happy to try to kill Crosshairs even though he believes in trying to come to peaceful solutions without violence (before promptly stabbing a prisoner of Lockdown). Some how magically (we don't actually see it happen) can change between robot, car, AND helicopter. No explanation given, he just does it. No trans-scanning involved either as both modes appear more than once.
Crosshairs - More pissed off with the humans that Optimus. Happy to leave us to our own devices. Also happy to kill Bumblebee if it meant he could take over leading the remaining Autobots (before Prime's return)
The Dinobots - Prisoners of Lockdown, freed by Prime who then had to beat Grimlock into submission. Have no lines at all aside from occasionally roaring. Are INCREDIBLY MASSIVE on the big screen. Definitely need to see more of them.
Lockdown - Interesting character, works side by side with the CIA to hunt down those who fought in the Battle of Chicago, his main goal however is to capture Optimus Prime and return him to "The Creators".
Galvatron - Named by the humans, but is Megatron reborn. Voiced by Welker, is far from the main protagonist in this movie.
Ratchet (deceased) - Hunted down by the humans, Ratchet is wounded and unable to escape, allowing Lockdown to murder him.
Confusing and annoying bits
• Sparks and Souls - When Lockdown murders Ratchet, he does so by ripping his spark from him. Later in the movie when Cade is repairing Prime he mentions his "power core" to which Prime tells him it is his power core and his spark which contains his memories.
Flash forward to the Galvatron/Megatron reveal, it's explained that Megatron downloaded himself from his severed head into his new human built body. No spark involved
• The Creators - Despite the hatchlings in Revenge of the Fallen, we're now told that Transformers are built, not born. The Creators are not revealed, though Prime leaves the Earth in search of them.
• Prime leaving - Despite being tired of humans hunting them, Prime leaves at the end, rocketing into space in search of The Creators, leaving the remaining Autobots behind to look after Cade and his family...said Autobots which also hate humans.
• Transformium - The name given to the metal that the robots are made out of it. I'm sorry, but that is a completely stupid name.
• Pangu Plaza - Nothing annoying about it. I just wanted to note that they could have cute the Pangu Plaza stuff out and it would have made NO difference to the story line at all.
Overall though I enjoyed the movie. I felt it's the best so far. As far as lead actors go, Mark Wahlberg and Nicola Peltz worked better than Shia LaBeouf and well...anyone. Primarily because Cade is trying to protect his daughter as opposed to Shia being a immature idiot lusting after anything with boobs.
It's definitely left things open for the next movie, that could involve a Earth based story with less Prime, or a Prime centric movie off-planet. Here's hoping for the latter.
