I don't enjoy Paul puzzles on the whole, and that certainly included this one. I have question marks all over the place. I should have known there would be problems when my first two - 9a and 23d - were fairly obscure words, and my third - 20d - turned out to be wrong (HOT TIP works nearly as well, apart from the plant).
Lots of film references - not up my street. Does the film of that name excuse the lack of a foreign language indication in21d?
I won't ask about all my queries, but why does "state" give the first 4 letters in 7d?
