The amount of emphasis that's put on Davros' disabilities here really doesn't feel great. A lot of this short is Jack kind of going 'Yeah he looks frail, and yeah he's in a wheelchair, and yeah he's only got one hand, but he's STILL DANGEROUS', which, I mean, yeah, but you dont' need to say all those first things.

Again the fact there's a lot of information and footage from classic really helps this short, it's just an overview of who davros is and what he's done, but it's not all information you really get to the same degree in Stolen Earth/Journey's End.
