Gonzo’s review published on Letterboxd :
That opening scene at Cybertron is better than anything in Bayformers and everything Transformers fans have ever wanted.
It's just too bad that Bumblebee never quite finds its rhythm nor does it escape the shadow of The Iron Giant.
Nonetheless, Bumblebee has all the right parts, and its heart is in the right place, and that alone makes it an improvement over the rest in the franchise. It's not perfect, but it's a start. Worth checking out.
