Well Downey jr writers did him proud. He gets the hero's send off. With Peter Parker calling him Sir enough to preen his ego. In fact spiderman loses his mask at an alarming rate every time a gust of wind goes by, just so we remember there is an actor behind the mask. It's a slow burn if a film that leads up to a good all out fight. Thanos finally bears his teeth at the end and shows his power. For me an adolescent spiderman spoils what is an adult avengers film.
