Oshi no Ko: 3 episode review (2-hour 15-minutes into the anime).
Many ambitious anime start off with 45-minute (1-hour timeslot) double-first episodes. But Oshi No Ko unusually reserved
four timeslots for a 90-minute quadruple first episode. The shear audacity of this anime stood out this season, and I wanted to get in on the action.
First and foremost: the quadruple first episode is a little bit slow, but not outrageously so. I think it's natural length should have been maybe ~70 minutes (triple-first episode) rather than 90. Otherwise, the plot is bonkers enough to fill up the whole time, and I think gaining a deeper understanding of all the characters is important. Why? Well, this show is basically an Idol anime crossed with a murder mystery thriller. Despite the crazy crossover in genres, its natural to need to cover all the main character personalities, including the managers, producers, and other people involved in a production. (From an "Idol show" perspective, those personalities are key to trying to become a star. But from the "Murder Mystery Thriller" perspective, learning the characters is necessary to find the whodunit).
For "fair warning", I should note that this anime is definitely feeling taboo and uncomfortably so. Ai herself is a teenage pregnancy case. An up-and-coming idol who somehow got pregnant at the age of 16. Her manager tries to hide this pregnancy from the public, etc. etc. Without going into spoiler territory, two important murders happen, and the main character Aqua resolves himself to try to solve these murders. The father of Ai's kids is likely involved, and thus the Idol plot and Murder-thriller is so linked.
Despite the "touch" of thriller revolving around these two murders... the bulk of the show remains focused on idol / production issues. Ai's manager trying to hide this teenage pregnancy case from her fans. Ai struggles with being authentic, considering most of her performances to be "pretty lies to the camera". The overall "feel" of this story is extremely jaded, with actors, idols, and producers feeling the fake-ness that they present to the fans.
All in all, I think its a reasonably competent drama. But between the uncomfortable taboos, and jaded outlook... I don't think this is a show for everybody. The more mainstream "murder/thriller" parts of the show are a relatively small part of the show. The only way you're really enjoying this is if you like the Idol/Drama parts.
If this sounds like something you can get into and take seriously, I think its an entertaining watch. The visuals are exceptional, watching Aqua (main character) play detective is exciting (though rare: his main job is his acting gigs). And the "babies with full adult minds " mechanic may have been done a bunch today, but its always fun.
