It is entertaining in the broad sense but IM3 success is kinda disconcerting for the future standard of Marvel movies.
IM3 should end up with $370-375 million but its breaching $400 mill would send signal to studios: "Hey, look, we don't
have to try so hard.." Based on what is onscreen, IM3 only deserves to make what SM4(TASM) did last year $260 million.
IM1 is still the best, half of IM2 is still better than the uneven IM3. I hope Marvel/Disney would strive for the genuine myth
making of Nolan's BATMANs
