What?
Are you fukking serious?
There's a guy with a suit of armor that's powered by a device that has the power of three nuclear reactors and it can fit in the palm of your hand.
There's another guy who is the pinnacle of peak human performance and was alive during world war II.
There's also a guy who can grow to 8 feet, turn green, and add a couple of hundred pounds of muscle to himself when he gets mad.
There's a fukking Norse God who wields a fukking magic hammer and can summon lightening when he feels like it....
BUT A fukkING ROBOT THAT MOVES HIS MOUTH WHILE HE TALKS IS UNREALISTIC?!?! That's where you draw the line?
