There's been good and bad in the Rockwell reign.
Bad: Rockwell doesn't seem to know much about ballet, in technical terms. Now, I don't think he should have to be able to throw around step names etc...several great critics didn't use a lot of dance terminology, but they were able to explain what they saw in an informative or even evocative way. Yes, he writes for a general audience and not ballet followers only, but sometimes his copy reads "he spins well, she jumps high." So, looking for depth there is pointless.
Good: Rockwell has taken to writing critics' essays on Sundays, hitting upon an interesting topic.
Bad: His arguments are usually half-thought through, full of holes. He'll also make pronouncements like "classical ballet is dead" and then he'll actually see a ballet and write "you know, this classical ballet aint half bad."
Good: He's gone on the road to review the companies in Boston, Seattle, Portland etc...
Bad: He's brought the above described to those reviews.
Good: He's brought in more writers. Sometimes during the season, they'll be several dance stories.
Bad: Some people have complained about the tone of those newer writers.
Good: Those dancers, companies etc.. that were receiving protection by Kisselgoff don't get the same treatment by Rockwell.

I'd second some of the venues mentioned by Alexandra, such as the reviews in the Wall Street Journal, New Yorker, Ballet Review, DanceView, Dance View Times, ballet.co.uk magazine and the like.
