Yeah, the Snowden leaks happened a month after Season 2 finished. I remember thinking "shit, I like Person of Interest, but I don't want it to be real."
Of course, if the real NSA was run by a benevolent omnipotent ASI with the voice of Amy Acker, I think I'd be more OK with it.

I distinctly remember wondering what had happened to Greer and Decima, and foolishly assuming that they had just given up after the loss at the end of season 2. Him appearing at the end of "Aletheia" was probably the biggest "oh, shit" moments I'd had since Root revealed herself.

4C was the perfect light rebound episode after the intensity of Endgame/The Crossing/The Devil's Share and Lethe/Aletheia. The episode is even better if you drink whiskey every time Reese tells the flight attendant to give someone a glass of it.

I was introducing the first season to a friend of mine a few years ago, and I had told him to that the reticules had meaning (though I let him figure out that meaning for himself). One of my favorite moments from that weekend was when he turned to me halfway through "Firewall" and asked "Wait, why does she have a…

"Because she believed in me! I'm not gonna throw that away for a piece of crap like you."

His speech at the end is probably my all-time favorite moment from the series. And there were a lot of good moments.

That's a solid scene, but I still think Fusco's speech to Simmons would have to rate as my series high-point.

I think the best spinoff would be to wait for a few years (i.e., until Westworld was done, which would hopefully last a good number of seasons), and then to have it take place in New York, with Captain Fusco in the Finch role (not the hacking, but the "guy in charge" role) organizing a team of former bad guys looking…

I'd like to imagine the Machine setting Fusco up as the captain of a precinct whose members are mostly composed of dirty cops looking for a shot at redemption by preventing violent crimes from happening. It would be a solid bookend on his character: the student has become the teacher.

I would love to see a continuation of Cyborg Shaw and the Machine taking down relevant numbers one at a time.
I still maintain that Shaw's brain chip makes her even more of a cyborg than Root was.

I thought only the last one tried to actually kill him; the others just lied and tried to escape.

"The Machine that tried to murder Finch." "The Machine that ran on Sony product placement."

"Did you know?"
That line reading from "God Mode" always gets me. Michael Emerson is a damn fine actor.

The reaction of the Nigerians when he asked if they were actually planning to kill them ("Uh… probably…") always gets me.

"Pазговоp" (or "Razgovor" if you don't like Cyrillic). I also loved how the show was unafraid to use nonstandard characters in its titles ("/").

Elias is apparently the second most frequently appearing recurring character, after Greer.

I think it's probably more like version 44 or 45 by this point (unless you count the pre-January 1, 2002 versions as alpha/beta models).

It definitely looked like Samaritan made it to the satellite and was starting to come online when the Machine jumped up there and hacked it to pieces. I think Harold was sent to the nearby building because A) there weren't any other eligible transmitters in the area, and B) it would confuse Samaritan into thinking…

I don't necessarily think that it was pre-planning, but I can definitely see that being something they realized was a possibility and steered towards it. They certainly have been implying that Samaritan is in many ways less sophisticated than the Machine (such as the way the two of them handle simulations), and the…

My first PoI comment was on an io9 recap thread (back when they did TV reviews). The site is hard to search, but I'm pretty sure my first comment was regarding Agent Donnelly's SSN in "Prisoner's Dilemma:"
