My friends and I LOVED the scene at the end (though isn’t that Samuel L. Jackson?) because it set up a sequel/spin-off Avengers movie =D
Actually, I really like the entire movie. It reminded me a lot of Transformers, but with a little more of some important things like plot and writing and character development instead of just being a couple hours of special effects. Plus, Pepper has to be one of my favorite female characters in a superhero movie ever.
The founding members of the Avengers were Iron Man, the Hulk, Thor, and Ant-man and the Wasp. The Hulk is coming in June, Thor is in the works, so figure it will all tie in with the Avengers
