Is It Any Good?

Our review:
Parents say : Not yet rated
Kids say : Not yet rated

It's a classic detective series in every way—except the protagonists are kids, and the scenarios are simple everyday events. Mystery League is very similar to the Australian Netflix hit The InBESTigators, with more diversity and without the mockumentary style. Instead, the cases are told linearly, in a way that prioritizes younger viewers.

The relatability of setting and characters can inspire a desire for learning and a sense of imagination; that everyday problems can be viewed as mysteries, making life more interesting to solve. Bonus points for the strong sense of community and appreciation of different cultures. This show is a good choice for family co-viewing.
