Yes, i can. Twilight is as big as Batman on opening day. New Moon bested TDK's OD record.Btw, the last Twilight did i believe 41m post-midnight, which is less than TDKR.
I haven't read anything about poor walkup business with the exception of Lordmandeep and no offense but who knows if he reads the data correctly and he's not even in the USA.
Well, it is not. But as far as superheroes go, Batman is the most frontloaded (again, i'm talking only about the internal weekend multiplier). If midnights go from 18m to 30m, obviously the post midnight gross wont follow suit (increase by the same percentage).
It's perfectly reasonable. Midnights are bigger (as is the trend with all movies), the post-midnight gross is about the same as TDK. Similar to how the Harry Potters behaved.
