Interesting if obscure, some good red herrings

I would very much appreciate a little more attention to detail. I was very frustrated that Dr was not accepted as an answer when the answer was Comic Book Doctors.

That has improved my knowledge of French physiologists by 400%

Andrew, every single one of those comic book doctors is correctly written as "Doctor". Some, who are called "Dr", were left off this grid by me for that exact reason. "Dr" would not be correct. And, surely, if you tried "Dr", you would know to try the correct version instead. Common sense.
