That was very fun! The jokes doesn't feel like some forced uncle humor like it usually does with Marvel movies, it blends in smoothly and serves the story. Great use of the source material, they managed to get a good background story out of Hank Pym/Janet Von Dyne to make for the 'passing of the torch'. Paul Rudd is great, as usual.
I would enjoy this so much more if I wasn't so tired of alternative, darker, dictator versions of super-heroes. As much as I'm bored by the general idea, as far as this trope goes this is one of the best examples.
Good world building. Not the best at the portrayal of female characters.
