Actually, critics didn't love Phantom. Well, at the time of its opening, they liked it, but since then the show has gotten lukewarm-to-negative reviews.
I would have also loved (and hoped) to see Les Miz on the top of the list. Of the four big British mega-musicals, Les Miz was the most critically-acclaimed. Even after 16 years, the show still garnered rave reviews which commented on how fresh and emotional the performances still were.
