Joss Whedon's The Avengers (Assemble) was the most fun I had at the movies in months, possibly years. Best superhero team movie yet made (good as they are, even the first two X-Men movies are really Wolverine movies). The problem for Marvel now will be topping it. Can't wait to see what comes next.
It's also a pitch-perfect example of giving everybody spotlight time. It's a great Captain America sequel, a great Iron Man episode, a great Black Widow movie - everybody gets something vital to do in the final battle in particular.
