It's not even just "meh", it's so bad that it is insulting

Rating: 1/10 (7 March 2019)

Brie's acting in this movie is the first thing that you notice, because it is just not very good. Now, when you put it against her previous works, it becomes so much worse. It is that bad, although I'm not sure if it's her fault or the director's.
The villain is uninteresting, the main characters lacks development and a lot of plot is very forced in a way that it is clearly constructed to show a strong lifeless female character instead of to tell a good story.
In the end, this movie is a waste of time, but it is speciall infuriating when it's demanded of fans to watch it before End Game.
I'd say, don't watch it; read the plot and skip this one
