I found most of this quite easy, but then came to a total halt with six clues to do, and eventually, reluctantly, resorted to this forum, and picked up a hint. After that everything fell easily into place. Well, at least all the answers fell into place, but "muscly pack" certainly didn't. I might perhaps have finished without help if I'd heard of either part of 15/16 (either the film or the 9). As for having nothing against "puerile smut", personally I do have something against it, not because it's smut, but because it's puerile. I find it rather irritating to be implicitly invited to giggle over something which one could reasonably be expected to have grown out of well before the end of one's teens. Having said that, it is my only complaint about Paul; it is a small defect to set against his much larger strengths as a setter, and I always enjoy his puzzles.
