TLDR: "Transformers One" is a great film with lots of humor, emotion, and action. It has a good plot, good voice acting, and great animation. I would definitely watch this and would highly recommend watching it.
My review of "Transformers One":
As a kid who grew up watching Transformers, I easily say that "Transformers One" is by far the best movie I have ever seen. As a new incarnation of the Transformers universe, this movie is the best out of all of them. The retelling of the origins of Optimus and Megatron puts a whole new spin on "more than meets the eye". As a movie aiming at mostly original fans, for someone new to Transformers this would be a great film to kickstart a new interest.
The plot and storytelling was amazing and there were many unexpected cameos and references to the old TV shows. I really enjoyed how the movie stuck to the designs from the original comics and cartoons, as well as aspects from the other incarnations. The action sequences added along with the animation style was great and I loved the designs.
There was a lot of emotion and plenty of good humor throughout the film. The way that the movie introduced the characters made me re-love them all over again. The voice acting was also incredible. It definitely took some time getting used to Chris Hemsworth voicing the beloved Optimus Prime when I'm used to Peter Cullen but it was still great.
It was just great to see a young version of the bots we all know and love and how things started. I would definitely like to see some more films or shows with Galvatron and Unicron done later in the future. For an overall rating, I would give this legendary film a 10/10. This is a must-watch movie and something that everyone will love.
