Like the last four Transformers movies, The Last Knight is over-long and overstuffed. While screenwriter Akiva Goldsman (Batman & Robin, Lost in Space, The DaVinci Code) who came up with the story added some DaVinci Code like subplots to the film. Which has Anthony Hopkins sending Mark Wahlberg's character on a quest to find Merlin's staff.
The upside is that there's some nice visuals and set pieces. All that seems wasted on films that don't add up to much. Sarcastic Spoiler Alert: They all have pretty much the same ending for movies that are so epicly long. "My name is Optimus Prime and I will always fight for humans and their planet....blah blah blah."
Michael Bay, before the start of some recent movies at theaters bragged about testing the limits of IMAX for the viewers. Yeah when he did that, he let the writer of Batman & Robin worry about the story. The film looks great but is it great ? No.
There's some laughs and cool new Transformers and robots but the movie is so long with a scattered plot that the good points don't save it . You also have Josh Duhmel back and chasing Wahlberg and the Autobots throughout until he's suddenly not.
Plus why are the humans even still after the Autobots that saved them four times and are their best defense against the Decepticons ? That's something for example that makes the film a mess. Bay hasn't learned from making any of these movies. Never takes notes from a bad review and just presents similar movies each time.
It's like "screw you, I'm Michael Bay and people will keep seeing these movies. So I will make it longer, louder and add more explosions!!"
