I feel like we've actually hit the box office ceiling for MCU films. The first Avengers was a novelty and you didn't need to watch that many movies to know what was going on. This one, you had to have watched at least 3 other movies to have a prayer of truly understanding and enjoying what was going on. The further along the MCU goes, the more the audience niche is going to be solidified and less chance of a breakout at the box office. (I don't think Disney/Marvel is complaining, but the BO game is going to be a lot more predictable and boring.

)
CW did everything right and it's still pretty frontloaded. I think it's just the nature of what it is (a Phase 3 MCU film), as well as the market now. To have a prayer of seeing this in real 2D IMAX, I had to go last night - my third viewing in a week and a half. Usually I like to space my viewings out more, but i had no choice. Alice Through the Looking Glass is going to take all of the 2D IMAX screens this weekend.
I remember when TDK was in IMAX for
months and it was
amazing. Boy, those were the good old days, huh?

By the by, there were just as many people at the very last IMAX showing for TDK 5 months after release, as there was for CW last night after just 3 weeks.
