As a lifelong Pokémon fan, I've always wanted a show like this: a piece that explores the relationship between people and Pokémon in a casual setting. The GameCube's Pokémon Channel was really the first and only time I remember. Pokémon Concierge is a short but delightful slice of Pokémon media. There's no thrilling battles here. Instead we get Haru, a down-on-her-luck office employee who takes a job at the Pokémon Resort for a change in scenery.
The series artfully blends cute Pokémon visuals with stories about how Haru helps Pokémon and in doing so learns a little about herself. At around 60 minutes total runtime, it's a must-watch for ANY Pokémon fan, regardless of age.
If I had one nitpick it's that the first episode is far weaker than the following three as it serves as mostly introduction.
