So, robots blasting each other in the face, body horror and reckless child endangerment is "meh, whatevs?" but this gets censored.
Oookaaay, BBC.
On a side note, Earthspark is such a neat show. The sound and visual design is fantastic, the voicework is top notch and the animation is really well done. There's a series one episode where the Seekers are attacking Prime and Megatron and it's just pure visual poetry.
