My favourite part was the callback to If-Then-Else. When Samaritan gives the Machine 1 minute to reveal its location, from the Machine's perspective, there are endlessly scrolling options of how to save them all, followed by the Machine making a decision.

Yeah, it was the Season 1 midseason finale when he died.

I don't know why, but this episode didn't really click for me. It just seemed like the episode was an hour of Carter saying "Don't get out of the car, you idiot!" over and over.

Of COURSE Agent Coulson is always early.
