It is really well done considering the scope of the whole MCU. It is a lot better than Black Panther that scored a nomination for Best Picture at the oscars, so this will get one too. The heroes who are gone will be missed. There will never be another first fleshing out of the Avengers, this series of movies is something special. A chapter movie, a grandiose finish.
I gave it 4 stars after first viewing, but then had to watch it again a few days in a row. Not obliged, felt the urge to. The last scene is perfect.
Closure, and yet the seeds planted for phase 4 are very promising.
