You really don't need dialogue to follow these movies, just laugh when everyone else does and assume the pretty white guy said something glib after destroying something/somebodyGonna see Avengers/Avengers 2 in a double feature at an imax today with Jun. She's gonna brave this no subtitle no Chinese world.
and the ending is always "they have to destroy the thing before the person does a thing with a thing" and things are always weird and glowy
although, a lover of one of the Avengers literally says "You know I totally support your avenging....", so there's that.
