Iron Man 3 - the final chapter?

The third Iron Man movie is much much better than the second one, but not as good as the first.  The script is better and the plot makes sense for a comic book movie.  The quips are there, the drama is there, the action/CGI sequences are there, but after the genuine surprises and humour of The Avengers, this third outing of fan favourite seems a bit tired.  I think it is just superhero fatigue.  If this set of movies were a standalone group of films rather than part of 10 movie franchise, it would come across better than it does.  It is just too heavy on the formula and relies on the charisma of Robert Downey Jr and the rest of the cast to lift it out of the by numbers plot.  Special mention of Ben Kingsley, who is just brilliant. The humour is there, but not in the burst out laughing way, more in the wry appreciation of a well delivered line. It feels a bit rushed at the end, as the wrap up after the major confrontation is a montage, glimpsing at decisions and impacts on the characters that would be major plot points in any other movie.  At least Gwyneth Paltrow has more to do in this outing.  Don't get me wrong, the movie is fun, but not 'I can't wait to see that again' fun.  You certainly get the sense that Tony Stark's story is at an end.  It will be interesting to see what happens in The Avengers 2.  Good luck Joss Whedon.
