I don't mind sound in space when it doesn't affect the plot, but Megatron's groan got Starscream's attention. That bugs me.
Skyquake's cockpit and wings bugged me too.
And I'm going to chalk Starscream hearing Megatron to acute audio sensors.
Starscream going on about warriors in stasis was making me hope that they were slowly building up the Cons. I was afraid Skyquake would be a one episode villain, I hope he somehow comes back.
It amazes me how much I enjoyed Soundwave just standing there, Starscream tells him to ignore Megatron's signal and just one radar ping breaks him.
Ratchet's crazy, I guess that shows how little he knows about Earth if he thought that volcano was a good idea.
