One more minor obsession

The Guardian has started a list of the top 10 mentions of crosswords in fiction, with No 10: Brief Encounter.
They note:

Brief Encounter is number two in the BFI's pick of the all-time best British films. While undoubtedly impressive, it is a picture viciously critical of crosswords, and so can come no higher than number 10 in our list

and in passing criticise the use of crosswords in Hot Fuzz too.
Here are the final scores for Brief Encounter:

Accuracy of portrayal of crosswords: 4/10
Positive attitude regarding crosswords: 0/10
Importance of crosswords in plot: 6/10
