I'm sorry but the first Transformers from Michael Bay had more texture than this movie. This is true at every level, but especially at the most detailed level and the most general one. At the most detailed level because of the design of the robots. Michael Bay's robots looked like they were actually made of metal. They were dirty, mechanical, brutal. Bumblebee's robots look like they're made of plastic. They're slick, clean, almost organic. The opening sequence on Cybertron is a perfect example of action I dislike, because it doesn't look anywhere near real; it's almost cartoon-like.
It lacks texture at the most general level because Bumblebee desperately lacks action, but it is an action movie. It therefore suffers from the same problem any action-less action movies suffer from, which is a crappy screenplay that leverages verbosity, clichés, and gimmicks to tell whatever banal story it wants to tell. I'm bored. I'm never bored during a Michael Bay movie, and especially not during Transformers, because when Michael Bay isn't filming a sunset, a supercar, a sexy model, or throwing crappy jokes (which is still better than banality, the guy is like an auteur on his own planet), at least he makes great, lengthy action.
See the scene where Bumblebee goes into the house and awkwardly breaks everything because he is too big, too violent and too goofy? See how this an enjoyable moment as a spectator? Well, this is what Michael Bay did to cinema with Transformers and this was also very enjoyable. Bumbleebee is more like the scene where Charlie puts a tape from The Smiths and Bumblebee rejects it because it's overrated boring sentimentality.
