Some very good action scenes in a cliché script about family and sisterhood, but too sluggish in parts and with lack of 3D features in some characters. Also, overlong by 20 or 25 minutes: editing out the hay and including those scenes with Iron Man, would have gained this movie much needed rhythm. Overall, one of the weakest deliveries -and out of synch with the other films- of the Marvel Cinematic Universe.
