The Disastrous Life of Saiki K. is the exception that proves the rule when it comes to shows on the anime list. Where all others are ~24 minutes per episodes, these are are about 5 minutes each. This is how I managed to watch 120 episodes in the space of a few weeks.
When this aired originally aired in Japan it was (usually) one episode per weekday, with a weekly omnibus airing later. It makes for better viewing to see them as bundles, especially when they do a bit of serialization – otherwise I can imagine it getting a bit hard to follow, which was my issue with Senyuu.
Much like Nichijou, this is a gag anime – it’s just that all the 5 minute vignettes are led by the same character: a deadpan high school student with ridiculously powerful psychic abilities called Saiki Kusuo. The episodes mostly centre around him trying to avoid his annoying school mates, eating sweets and trying to look as average as possible without his powers getting in the way.
What powers does he have? Well, pretty much everything you can think of. Telepathy, teleportation, clairvoyance, pyrokinesis, super strength… the list goes on and is added to as required in the episode. I actually like the idea of having a character (much like Saitama in One Punch Man) where the joke comes from them being so ridiculously overpowered. It makes a nice change from more serious shows where they derive drama from limitations.
On the whole this series felt like a good diversion. Sure the jokes were silly, but after time in the office you need to watch something a bit goofy. It would be interesting to see this as a proper length show, but I can see how dragging the storylines out for a half hour would negatively affect the series.
