What they got right: Steve takes on the dual role of writer and primary artist (he has help inking one to three of the 3 parts) and does a great job with both (although he seems to be missing the external "Police Box" writing on the TARDIS). The fire-spraying creature in the final panels work rather well for the period.
What they got wrong: When we first see it, however, he's dressed in a hood and nothing else, which just looks weird. Also, I don't know if it's the inks or the added IDW coloring (not having seen the original, which was in black-and-white or the Marvel color if the US comic ever reprinted this storyline), but there are times the characters look over-shaded, if that explains what I'm thinking. It's not that big a detraction, but it is a slight distraction at times.
Recommendation: I would love to see a current Doctor story by Parkhouse. Is he still alive and writing?
