Iron Man / Tony Stark is not exactly my favourite Marvel character, so I skipped the “Iron Man” movies so far. Actually. In “Iron Man 2” he is not so bad. Perhaps because he is a bit of the tragic character.
In “Iron Man 2” we have both Gwyneth Paltrow (as Pepper of course) and Scarlett Johansson (as Natalie Rushman / Natasha Romanoff, apparently not yet “Black Widow“) which is a plus. And Mickey Rourke is an amusing bad guy. We also see the dawn of the Avengers, as Nick Fury (Samuel L. Jackson) yet has to recruit Iron Man for his team.
For the rest, Iron Man is hunted by Ivan Vanko, plus the competition tries to outsmart him. Together these opponents wreck havoc which Iron Man sets right, without the help of the other Avengers, as that team appears to be non-existent yet.
So perhaps “Iron Man 2” fits in the larger Marvel story and was it a good idea to watch it after all. I suppose I might now also watch “Iron Man 3” (2013).
