jack black movie "school of rock" opens on saturday... bad sign?

[dolph]

i don't recall ever hearing a movie open on a saturday before. the only explanation i can think of is that it's so bad, critics would have destroyed it had it come out today, and perhaps reviews don't get published on the weekend. yet rotten tomatoes gives it a 91%... so what gives?

Its so good it has to have a 1-day handicap.

Its a sneak preview not an opening.
