Of all the Marvel movies that have come out in the last 10 years I thought that this latest entry was the weakest by far. The movie plays like it was made for TV and even though some of the special effects were good, they were not nearly as good as you would expect from a Marvel comics movie. Overall, I thought the story was rather boring in a number of scenes and dragged on too long in others. Paul Rudd is good in his role but despite that I doubt that this movie will become a franchise with many sequels like Spiderman, The Hulk, Ironman and the Avengers.
I cannot recommend this movie.
