This story follows the Master as he tries to take on companions and be a hero like the Doctor. Which is a neat concept in itself. The problem is that the structure of this story becomes very predictable. The Master finds a companion, tries to be a hero, fails and the companion leaves him. At first this happens in just a few paragraphs, but every time the Master tries the pattern takes longer and longer. It removes any element of surprise from the equation, which drags this story down a little. It might also be antithetical to the intention, but maybe a more defined Doctor and Master would help this story by giving the pattern more depth. As it is now, we have an undefined Master and an undefined Doctor battling it out. To achieve this, we have quite a bit of distance from both. No personal flourishes or reflection. I think that kind of reflection could have really helped raise the story to the next level, but as it is, it is still well done.
