DAY FUCKING ONE.
I literally only have one complaint so far, they don't use the old show's gun sound effects. Transformers had some of the absolute best sounding pew pew noises ever and they don't sound like they're even trying to emulate them. Sad.
For example, the regular Autobot sound effect:
I can't seem to find the Decepticon one or the Megatron cannon/Optimus Prime rifle sound.
Ahh, here we go. This scene showcases them all. Also, awesome 80's hair metal and a traumatic murder spree to kill the old toys.
