2.5 starts actually --- Not bad, but definitely one of the weaker MCU film along with Thor 2/Iron Man 2/ Incredible Hulk. Screenplay needed more work and characters feel unfinished. The action scenes are quite ordinary compared to other MCU films. It's advantage was the release time as it came between Infinity War and Endgame, which massively helped its box office success. Brie Larson, Jude Law, Samuel Jackson... all has better films.
