It starts ok but then it gets boring and I couldn't enjoy the ending which is quite epic. After the first 20+ minutes the movie almost stops. In a large proportion of time almost nothing happens or if it happens it is not so important even the villains seem to have a break from everything else to do nothing, everything becomes very slow and I felt like I was watching a Tony Stark's typical day. It also has good moments, as I said the beginning and the end, but I can't get over the fact that I almost fell asleep in the middle. I still like the cast and the introduction of Black Widow was well received, but I can still say that Iron Man 2 is one of the most boring Marvel movies.
