One of the best superhero films?

Rating: 8/10 (8 January 2013)

Partially, yes, it is among the best of the bunch. Though not on the level of Spider Man 2, The Dark Knight and Watchmen, it is definitely watchable and it is very funny, though it is not a masterpiece (in fact, there isn't any true masterpiece in terms of superhero movies: the greatest would be, perhaps, Watchmen, in terms of having a powerful impact over the individual who watches it).
The best parts of the film are the first two thirds, while the climax and the ending are a bit flawed and, as a result, the film loses steam and becomes weaker, I would have rated it 8 or even 9 if the momentum had been maintained until the end.
