So the Idea of Lenny Henry (who played a Parody Alternative 7th Doctor in the 80s) regenerating is a nice one and could have worked quite well. Sadly despite being a supposed to be comedic Story, it's just a straight-up Regeneration, is there a Joke made about him changing into David Tennant? No. Not really. Does it have Jokes? I.. I guess? But sadly none of those work me. Oh well.
