This is the best of the Phase 2 Marvel movies. It's what "G.I. Joe: Retaliation" should have been. While its definitely the most serious of the movies, it still manages to have little moments of subtle humor that we've all loved since "Iron Man." Nick Fury plays his biggest part yet in this movie, and Black Widow is an important factor in the plot as well. Even though this is a superhero movie, it's not just turn off your brain and enjoy. It has a complex plot that you have to pay attention to. As always stay halfway through the credits, and until the end. Both scenes are extremely important to the future of the Marvel Cinematic Universe. Grade: A- 9/10 4.5/5 stars
