Tony is creating an artificial intelligence system to defend the whole earth from alien invasions and accidentally gives it sentience using one of the infinity stones. Predictably it immediately gets the wrong end of the stick and decides that protecting the earth means something different from not getting people killed.
Oooh, Infinity Stone! Yeah, zero recollection, so thank you. And reminds me of the evil robot Santa from Futurama. ;)

As soon as we get to that point it's boring, but the argument about what Tony is doing and why is actually quite good.
That does ring a bell. A very faint one though.

It's getting to the point where I'm preferring the super heroes who just pop up without their own dedicated movie because so help me, I do not care.
And so say all of us! (With the exception of Wonder Woman, and any female superhero, really.)

Also, another origins story, another shoehorned, underdeveloped love interest. I hate everything.
Boo. Make them all bi/pansexual and make them hook up with each other. Fewer female characters, true, but more LGBTQ+ representation!

The bits where he's telling a story in voiceover and all the people in the story are lip-synching along to his slang-y retelling of it: I know that's a pretty standard joke, but it's one of my favorite executions of it I've ever seen.
Like I said - I like Antman, but damn, why does the Mexican guy not get his own film?

That was great. They way they kept bringing up the tropes of that kind of fight and then inverting them over and over was fantastic.
The payoff for watching all the generic stuff is great. :D
