Credit goes to Asimov for subverting the traditional robot takeover scenario.
When the robots break into the police station, the Chief does not stop to question why. He pulls out a shotgun and blows two away, in SLOW MOTION, no less.
Sunny is carrying the Vitally important nanites that will save the world from robot invasion,and he runs into two robots. After dispatching the first one, he tosses the nanites into the air, tears the second robot apart, and then catches the nanites before they hit the ground. In slow motion.
When the main character slides down V.I.K.I.'s network and injects the nanites. It is only made more awesome by the last line from the villain, "My logic is undenia..bl..e"
Although the main character's retort wasn't without awesomeness:
VIKI: You do not understand. My logic is undeniable.
Del: You have so got to die.
Really, every action scene in the entire movie is a CMoA, especially the highway scene, due to Spooner's absolute refusal to die.
Right after the highway scene, Spooner is sitting down and then a surviving robot suddenly tries to crush him with his car. The robot misses but proceeds to kick Spooner's ass. Finally, the robot corners Spooner, takes a pipe thing that Spooner had been fighting with from him, and starts to whale on Spooner's raised arm. Spooner shows no physical damage, even though these robots have the force to dent metal with their fists. The robot looks at the pipe with a "what the hell" look. Then we see Spooner's arm flashing sparks and it's metal. Spooner then sarcastically goes: "Yeah". Cue awesome music and a beat down ensues.
Sonny. Cracking a robot's skull with the crook of his elbow, throwing another through a sheet of glass, and jumping at high speed down a bottomless pit to save the girl. He pretty much is a Bad Ass in the truest sense of the word, yet retains his sense of morality and duty.
Sonny didn't have anything to be afraid of, jumping down a bottomless pit. After all, he's a leaf on the wind.
The scene when the citizens of Chicago band together to fight the NS-5s. Even when they get their butts kicked it's still awesome.
The older USR robots fighting against the NS-5s. They seem to be pretty capable of fighting them, but the NS-5s were too strong for them. One older robot grabs Spooner's leg, telling him to "run". Then the NS-5s chase after him, Spooner runs past some storage containers where more of the older models jump out to protect Spooner, slowing them down.
Spooner managing to escape a house being demolished by an enormous robot...and saving Lanning's cat in the process.
Somehow "I told you so" just doesn't quite say it.
