I couldn't agree with you more. All that talk of Batman Begins legs have flown out of the window and the movie only went up against a movie that opened with an estimated 37mil. I think that it is being well regarded but it is frontloaded and maybe the word of mouth isn't as bullet proof as we believe it is.
Next weekend is really going to be the real test for this film, is it going to hold up under the weight of GL, which will open with over 50mil? It needs an early 40's drop and then needs to stablize into those kinds of drops for the rest of it's run. If it drops another 50+% it is f**ked. Plain and simple.
