For those who aren't used to a Satoshi Kon anime, be prepared. They usually start off as a normal type of anime, and then take a serious turn for the surreal. As for Paranoia Agent, it starts off as a normal detective-style anime but then the plot twists and turns worse than a twist-tie on a bag of wonder bread. For those used to Satoshi Kon's work (Paprika, Tokyo Godfathers, etc), none of this is news. Personally I enjoy a good "whodunit" anime since I also love CSI, 24, Prison Break, etc. These kind of shows actually get the viewer to really think how its going to unfold next or guess who is the real culprit. Just for general information I watched the whole show on Cartoon Network years ago, but then I rewatched the Japanese version and let me tell you there are ALOT of things they (Cartoon Network) cut in various episodes of the show. They even took out important parts of the show that were very important to making the episode make sense. But after watching the 'uncut' version many things made sense.
Even with that extra knowledge I couldn't help but think that half the episodes had a filler feeling to them. Many times you'll wonder why certain story arcs are being told or how that person is connected to the overall story but it will all make sense in the end (except for episode 09). The character cast is extremely varied, in terms of look and personality. The details show in most of their faces.Whats most noticeable is the older the character is, the more detail their face becomes. The voice acting in the english and japanese dubs are extremely top notch as well. For the serious otakus you'll definitely notice Mamiko Noto's voice or Haruko Momoi, but if you're open minded enough to listen to the english side of the voices you'll notice good voices as well like Carrie Savage or Sam Regal. But the attention to detail don't just stop with character style and voice acting.
Character props and background art is where this show shines the most, from an artists cluttered cubicle to an otaku's room filled with figures. I could have sworn you can actually see a layer of dust on an old bookshelf. Each scene is unique and different and you can tell they put alot of time and effort on all the small details to make this show stand out better than the rest. My only gripe out the artwork is that it is very earth tone and dark. Well not really dark per se but its color scheme is very warm and brownish looking which I didn't like all that much but you will soon overcome the problem the more you watch it.
Another gripe I am not to fond of how Kon draws his characters. Some of them look very normal, ordinary and sometimes cute. But the characters who wear their personality on their sleeves look very drastic. Like abnormaly huge mouths, beady eyes, fishy lips, all very strange to look at. The most that suffers from this type of look are the male figures in the show. I'm not fond of it but im sure most people will enjoy the change of pace from all the cute moe cartoons that plage the anime world.
If you have never seen a Sat-Kon anime, I highly reccomend watching this series simply because it will definitely be a different experience that you should see for yourself. With the outrageous plot twists and holes in some parts, the story does have a few problems overall. Like I said way back in the beggining the story starts out fine then it takes a serious turn for the surreal so take that however you may but I highly recommender this to anyone who doesn't mind a crazy mind trip of "Alice in Wonderland" proportions.
