Terrible. Just terrible.
Please, destroy the memory of the original cartoon more.

Terrible animation, horrible cheap brushed metal textures used everywhere. Looks like some kid textured the models in blender.
Whilst the robot models are true to the original, which they can be commended on at least that, the way they move against the background, and the backgrounds themselves, are really bad.
The model design almost too far into the realism and it looks like they are using the actual plastic toys as models.

Terrible sound effects - the robots make these weird clunking and whirring noises as they walk, and they move strangely, as if lunging around.
Voices are terrible too. And whats with the reverb and echo. Even in the 80's they had better voice effects.
The characters don't have 10% of the personality or believeability of the original cartoon.
All in all seems a contrived cheap knockoff of low quality compared to even a cartoon written 36 years ago.

I don't understand how companies keep ripping off the transformers idea and mucking it up. It's not that hard.
