*BRAVO MCU*
Every war always ends up with casualties. Some will be lost and some will be won. Part of the journey is the end. Captain America aka Steve Rogers and Iron Man aka Tony Stark really grafted it. I think there could have done more action with the other Avengers. Thor could have been THOR. Hulk more HULK. Black Widow has a good spinoff for her new upcoming movie. A bit like Elecktra for any Daredevil fans I think. (Just a speculation on Black Widow here).
They could have made the plot much more edgy. Showing the other side of the snap i.e. what happend to the Avengers taken by the snap. Where where where? Too much power was emphasised on Thanos. There could have done more action to give the movie more kick. Hail Hyda and Long live Iron Man.
Good prevails.
