In particular, given that this was the first MCU movie since The Avengers, it was a considerable step down, thinkwise.
Nonetheless, worth seeing.
Stark is still sharp. There are a smattering of good one liners, e.g. "Laurence Oblivier".
Kingsley is great.
For the first time in the Iron Man series, a plot device is introduced that makes no kind of physical sense to a scientifically literate person. Relies on gobbledegook and magic. I can handle that in the _mixed_ milieu of the Avengers but it feels wrong in the down-to-earth Iron Man movies.
