    Craftsmanship that we don't expect from network television

    Kudos to Nolan, et al., the writers and actors for this episode, If-Then-Else, which competes right up there with any episode of The Americans, Homeland and other cablers whose greatness everyone knows about **because we hear it all the time**. We do not hear much about PoI from the talking heads and it is certainly no media darling, perhaps because it is a CBS show, or because Jim Cavaziel's Reece's expressionless monotone, or maybe because many critics wrote it off early in the first season. I am glad we stayed with it, as over the years this show has become not just a strong ensemble piece, but one of the most tightly crafted dramas airing on television. And those characterizations that annoyed critics the first season (Reece's grumble-like monotone, the idea of an all-knowing government spying on us) either turned into an important part of the ensemble's interplay, or was revealed as a prescient warning -- "holy crap! the Government actually IS spying on us!"

    This uniquely structured episode rewards us longtime viewers with character-driven humor, with pathos and even a sly wink that comes right up the 4th Wall barrier, without truly breaking it. At the same time, If-Then-Else was filmed beautifully with the kinds of additional touches that one does not expect from cost-conscious network shows.

    Just, really good job to all involved in this roller coaster of an episode and thank you for respecting the intelligence, loyalty and discrimination of your audience.

    Masterpiece

    Masterpiece of storytelling. Comparison to chess game, "if" statement used in coding languages and simulation of parallel universes makes it my favorite episode of POI and one of the best I've ever seen, comparable only to best pieces of Black Mirror. Gem in TV shows history.

    One of Many Breathtaking Episodes and Probably Best So Far

    Huge fan since episode 1. Can't really add to what's already been said by others, it's my favorite series. This episode was movie theater quality - they should consider doing 2 hour shows as great as they have been. Every single episode I have watched of this show was top-notch, and the population at large that watches this show gets quite the "big brother" education along the way, not something that many action genres can lay claim to. The second you set foot outside your door in London, a camera + facial recognition software identifies you within seconds, to assume that situation doesn't exist here in America is foolhardy at best. This series may very well be the most prophetic of all in years to come. Acting is ridiculously top-notch - even from "bear" that great Belgian Malinois. It's the most solid 10 out of 10 in all of television right now, and should be defined as "required viewing."

    The best episode so far

    Outstanding episode. Others have summarized it pretty well. Very thoughtful and creative, great flashbacks and details. The final scene was heartbreaking and beautifully done, as were all special effects. We now have way more insight into how The Machine works. Root and Shaw were very sweet - Shaw always tries to pretend she doesn't care but you can just see it's not as simple as that. Or, as little Genrika said in Episode 3.05 "It's not that you don't have feelings. It's just like the volume is turned way down, like the sound of an old tape. The voices are there, you just have to listen." My favorite POI episode.

    I just wanted to add something - to the reviewer who said the show was ruined because "We are not into unnatural relationships. Two girls kissing is gross." ---- Are you serious? 'Bad code', as Root would say.

    one of Nolan brother's masterpiece...well written, well played.

    After i watched the episode i directly checked the writers and the creators. i did not know till then that this show's creator is of one of Nolan brothers. the younger brother .. the writer of Memonto... just brilliant... i watch so many maybe too many TV shows in these days but i have to admit this episode was one of the best i have ever watched. well they mixed up who is carrying the bag but that is OK i guess. the chess game lesson was great.. and we saw how Harrold thought moral values to the Machine... well written well played. big surprise at the end...i wish i can learn at least whose idea was this story... and i have to say it was brilliant. i enjoy the show. Thank you guys... i gave 10 pout of 10.

    • Quotes

      Harold Finch: On chess. "It's a useful mental exercise. Through the years, many thinkers have been fascinated by it. But I don't enjoy playing... Because it was a game that was born during a brutal age when life counted for little. Everyone believed that some people were worth more than others. Kings. Pawns. I don't think that anyone is worth more than anyone else... Chess is just a game. Real people are not pieces. You can't assign more value to some of them and not others. Not to me. Not to anyone. People are not a thing that you can sacrifice. The lesson is, if anyone who looks on to the world as if it is a game of chess, deserves to lose. "
