I won't pay my money to watch this

Rating: Null/10 (2 June 2019)

If this movie is available in any of the streaming service you already have, then give it a try. I still haven't watched Endgame, I can't say how much of this movie is useful for that(though from the movie I think none of it is useful). In my opinion if they introduced this character directly in Endgame and told us that she is powerful I would believe that.
If you are one of those people who would get enpowered by watching a movie, I would suggest Wonder Woman movie. Give it a try, I am not saying it's a perfect movie but the character depth and story are better written and joyful to watch.
