Danton Black was not as cool as Mardon was, of course, i like the way he "regenerated" but Mardon kinda did his thing way better than this one. The only thing I actually like in this episode is the end, how flash smashes him into that pole and al of the regenerated ones fall down like dominos. Then at the end of the episode Wells killing Simon Stagg, made it better. And the way Danton killed Java, but this one was not as interesting. Overall, this episode is not really good, I believe they can do way better than this as the ratings say. For the start, it is a good episode because to be honest, every series has the first episodes more boring than the others.
