If you've spent the last couple of years on the moon and haven't seen any of the MCU-movies, give this a try. Finally, Iron Man is still fun to watch and not just a vehicle to set up a franchise. So the movie doesn't feel as bloated as some other superhero flicks. More explosions and obvious cgi-effects don't improve a movie. It's set in a world that at least COULD be real which makes us care more for the characters and their actions. During my re-watch I also noticed how 'down to earth' this movie is if you compare it to some of the more recent MCU-entries. You can't underestimate this in our age of 45 mins battles at the end of movies. The final fight isn't stretched too long and therefore doesn't get boring.
There is action, humour, drama, world establishing, all in great balance. Is Ant-man really a changed man at the end of the movie? What about Star Lord? What about Thor? Black Widow? Hawkeye? Then again, you have to give it to the director that he really made a well-paced, well-balanced movie.
Of course, in an origin story it's easier to have your protagonist change but let's compare for a second: You need to give him a treatment, come on 74.33 of 1766 players like the mobile game. Hey, guys, do you like the super hero Iron Man unfortunately Iron Man was injured when he was fighting with the bad guys.
Tony ends the movie as a totally different person. You can play the game on smartphone and tablet (iPhone, iPad, Samsung, Android devices and Windows Phone). There is actually some sort of character development visible. A couple of things astonished me, though: First of all, a common mistake of the later Marvel-movies isn't made here. In my attempt to rewatch all the MCU-movies chronologically I began with the first Iron Man.
