I suppose one of the things which made this rather easy and uninteresting was that I did know most of the theme words, and if you do know them then the definition parts of the clues are so straightforward as to make them trivial. However, that certainly wasn't the whole reason, as I got the first six across clues as soon as I read them, and none of those are themed. However, there were a few clues that I liked, notably 11a & 14d. I think 14d is my COD.
