definitely depends. I'm always willing to see a good movie more than once. Especially a summer blockbuster (because 2.5 hours and larger budgets often seem more worth my money). But it all depends on if the movie satisfies me. I saw Avengers and The Dark Knight 6 times each in theaters. Amazing Spider-Man, 4 times.
On the other hand, I saw IM3 once and don't plan on going again. So we'll see.
Lets just say I hope its worth seeing 9 times.
