So, I just finished Season 1.
This was a slightly odd experience because I remember watching some of these episodes, such as "Strain Theory", when T'Baio first started independently airing these episodes before the show got picked up by The SFN. However, because it had been some time since I've seen those episodes, I felt like it was necessary to start from "the beginning", so to speak, and so I started with the very "first" episode, "The Origin of Dorthy Ascher", and worked my way up to the Season Finale, "Kiss & Tell".
The biggest difference I noticed was the addition of series composer Andrew Haughton, who has replaced Nine Inch Nails and composed original music for all of the episodes. It was a little jarring at first, but after some time I got accustom to it. Haughton does a good job at emulating Trent Reznor's style without outright duplicating it, so his music works on multiple levels while also creating a distinctive musical style for the series.
A major thing I had noticed, besides the music, was how the story was structured thematically with the new order of episodes. When T'Baio first started airing Posthuman, he started out with "Strain Theory", and a lot of Porter's past and his relationship with Gina was left a mystery, something I assumed we would learn later on throughout the series, as well as the revelation of the memes and so on and so forth. In a way, I almost like that approach more, because we gradually learned things about Porter and the past through subtle hints and clues, but the way this particular season is structured, we learn about the world (as well as Porter and Gina's relationship) early on, removing the mystery and mystique of the older approach.
However, at the same time, I can't really complain, because T'Baio has cast some excellent actors in the lead roles. Jason Martorino is fantastic as Charles Porter. He exhibits all of the characteristic traits you would expect in a leading man, and then some. He has the charisma and the vulnerability to pull off Porter effectively. He's instantly likable, which helps, too. Sara Mitich, who plays Gina, adds sophistication, wit and a cool charm to her character. Most of all, though, Martorino and Mitich have fantastic chemistry together. The "Promises" trilogy is basically an exploration of the Porter/Gina relationship and we learn about them and their dynamic whilst set against the background of this great sci-fi backdrop. Like all great sci-fi, Posthuman has a very human core, and while I think structurally it might give away too much too soon (at least in the context of the mythology and the later episodes), it's difficult to complain when you have actors who have so much chemistry and are so entertaining to watch. T'Baio does a splendid job at exploring who they are as people while also exploring the scientific and philosophical underpinnings of his intriguing sci-fi premise. Porter and Gina's relationship is really at the heart of Posthuman, and I hope to see more of her in Season 2.
Other than that, besides the re-structuring of episodes, the only other big complaint I have is the way "Kiss & Tell" was redone. In the original version of the episode, we had this great pulsating chase with awesome Nine Inch Nails music pounding throughout the episode. In the new version, that pulsating music is replaced with something a bit too soft and ambient for my tastes. The on-set audio has also been (for the most part) completely removed, taking away any tension during the actual chase (which makes up the entirety of the episode for the most part). I understand the addition of new music, but I have to say that I preferred the original version of this episode much more. It's a minor quibble, but something that bothered me nevertheless.
Overall, though, Posthuman is a very good science-fiction web series that delves into the psychological and philosophical underpinnings of its premise in a way that most contemporary sci-fi shows just ignore. It's smart, sharply written, with tremendous performances from its two leads. I definitely can't wait for Season 2, and since I've seen some episodes that I think were omitted from this most recent re-structuring, I think I have a fairly strong idea of where the next season is headed, but regardless, I'm still excited.
