Did you see Avatar's 33% first Monday drop coming off the all time Sunday record? And then it having virtually the same holds every day since except Friday? I sure didn't. In 2009 when Xmas fell on a Friday, only one movie dropped more than 30% that Monday. Avatar dropped 20%. Now that would be insane, but I definitely don't think a 25-30% drop is unlikely. Unless it is starting to hit that "wall" some of us have discussed, but remember kids are all still off and the post Xmas week tends to be better for movies than pre since people aren't nearly as busy.
