THE GREAT MARVEL MOVIE CATCHUP PART 7
This ramble is rated 7 by the LSBRC for sustained mild spoilers.
Tony is having PTSD and anxiety attacks following the events of The Avengers. He feels inadequate being just a man in a suit after fighting alongside (and against) genuinely super human beings. Interestingly his friends from The Avengers are conspicuously absent here, especially Dr Banner who goes off with Stark at the end of Avengers for some kind of R&D love-in but doesn’t show up during this film.
