If you have such wealth of acting at your disposal but reduce most of your cast to cameo appearances the story suffers. Some of the cameos were great to watch, they are the world's best known actors after all, but to me it was just a bit too much of everything and I lost interest when I lost count of all the characters, plots and subplots. I think I like it better when they focus on one or a few superheroes. High points of the movie: any scene with Tony Stark or Thor, but why use a star like Nathalie Portman when all she has to do is look pretty and walk around a bit, it makes you wonder whether these stars are short on money though. My grandson loved it though.
