One of the best comic book based superhero movies. It is a part of the Marvel Cinematic Universe, but unlike the other 10 or so films that have come so far, it has no continuity elements in common with the “mainline” story. What makes this movie tick is that it is just fun. Not taking itself seriously too much, lots of gags and wise cracks, but not just a series of poor jokes. Fantastic, and if you can see it on an IMAX 3D screen do yourself a favour and watch it in large format.
This movie is what Star Wars could be if it was made today.
