Just watched it last night. In my opinión it is a 6/10 at best. It starts extremely slow, you can deduct the plot from a mile away, and as usual Marvel movies, you see her in SSG form during maybe just the last 20 - 15 minutes of the movie.
The CGI in a specific scene where she was falling from the sky looked extremely bad, like ps2 level quality CGI, but that type of cut corners are always expected in almost all Marvel movies, Avengers 1 included. It is a nice histórico movie, as you see the starts of Fury and Coulson, but besides that it doesn't adds a lot.
And last, but not least, she is insanely poweful, to the point where one can even argue if the other characters are actually needed in Endgame to confront Thanos, so it will be interesting to see how they can manage to balance her out with the rest of the team, and more importantly, with Thanos.
