Several of these movies recieved really good reviews -- Avatar, The Lovely Bones, Precious -- but once they reach a certain level of popularity the critics always back off saying they are awful.
Sorry but you have it slightly wrong Boomerrang
. I read a lot of movie reviews (The Village Voice, Time Out New York, CSMonitor, New York Magazine, New York Press, The Onion AV Club, etc...). Reviews come out Thursdays and Fridays of the of the film's first theatrical weekend of release.
So technically they precede the box office popularity by a singular day.
did get a lot of rave reviews but it also got butchered by some notable critics as well.
