It's really interesting reading comments from other solvers, some of whom had very different experiences from mine. Very easy on the whole. Some clues took a bit of head scratching, but none of them were as tough as the most difficult ones usually are. FOI 11a, which I found almost ridiculously easy. LOI? Well, the last one for which I figured out the answer was 5d, but the last one I fully parsed was 21a, for which I guessed the answer almost at the beginning, but couldn't think why. I reckon 21 out of the 26 clues were thematic, which is a remarkably high proportion. I quite liked the way the theme was incorporated into so many clues in different ways. Unless I've missed something, the definition part of 1d is remarkably generic, so much so that I'm not at all happy with it as a clue, although I didn't find it very difficult to solve. Although I quite enjoyed the puzzle, like some others who have commented I really didn't find any clue clever enough to be a serious contender for COD, but if I have to choose one then maybe it's 13,8.
