I don't agree with this at all. He certainly could have rephrased them, and just been simple about it. His 'original comments' may not have been exactly 'cruel', but they were gratuitous; and I do agree with miliosr that there really is a whiff of John Simon here, if not quite what he'd say about Judy Garland's looks, etc. He could simply have said both 'appeared to have gained weight', and even that this was visually 'somewhat distracting', or suchlike. I don't think he even needs to relate it to 'how they danced' the way others do, and it's all right if he wants to write about how he found their weight gains 'unfortunate' or 'not looking good in the piece' or even just 'not to his taste'. But this stupid cuteness: "looked as if she had eaten one sugarplum too many" and "seems to have been sampling half the Sweet realm" is not necessary. Relating their weight gain to the ballet material and eating sweets is tacky in a twee and obnoxious way, not original IMO.
Macaulay aside, I haven't seen Ringer for about 4 years, so I wouldn't be able to say anything, but if Jared Angle really has noticeably gained weight, that does surprise me, and he had to do it really fast: I saw him in 'Swan Lake' in February, and he was so slim and svelte you were even quite conscious of it. I didn't find him a charismatic dancer in any sense of a strong princely presence, but his grande pirouettes were certainly something one couldn't argue too much with--they were there.
I think, however clumsily, it was 'in the context of the performance', even if not made as specific as with Seymour and Morris. I guess I just find his remarks on the sweet-eating silly. I don't like his writing that much, and this is aside from what his expertise in ballet may or may not be (meaning others will know better than I, although it would seem he obviously knows a great deal.)
