Doctor Who, Season Nine

[Esquilax]

The thing that perplexed me about the sonic glasses is that they felt they needed to destroy the screwdriver before giving them to Twelve, as though he can only handle one magic gadget at a time. Just let him have both, that way there wouldn't be this need to just replicate all the (increasingly complicated and nonsensical) functionality that the screwdriver had, just in a new form. You could give the glasses some new use so that they wouldn't just be "that version of the Doctor's magic wand that he wore on his face that one time."

That's what I liked about the psychic paper, or the Doctor's magic pockets: they were tools in keeping with the Doctor's character that had defined uses and weren't just another function enclosed in the omnitool that the sonic screwdriver has become. Otherwise it's like the Doctor just rolls around the universe owning like two things that just so happen to always have abilities that are required for the writers to get out of a given situation. You never feel cheated with the psychic paper because you knew what it could do and what it couldn't from the moment it got whipped out.
