I went and visited the Metallica board. THey were just gushing over the new album there. It cracks me up. It didn't seem very honest to me. Here, you have people who love the new THrax and some who don't and it's ok to discuss. Most of the messages there were very, very positive. i saw no scathing reviews of St. Anger at all. Come on, I have friends who won't even listen to the new album after hearing 3 or 4 songs. You can't tell me everyone on the board there loves it.
As for being number one--you knew they would be. First album in years from a hugely popular band with tons of radio play. The prior two weeks number ones were Marylin Manson and Led Zeppelin and Staind I believe.
