Saw "Batman: Rise of the Dark Knight" on a so-called "IMAX" and it was a total rippoff! There was no tall movie screen, only the stadium size screen for larger audiences. Paid $42 for 3 people to see IMAX in the suburbs. Could have paid less than $30 and pretty much received the same experience. Will try the theater at Navy Pier next time when I want a true IMAX experience.
