How to read it
If you're someone who slots slice-of-life shows on principle, Chiikawa Movie: Ningyo no Shima no Himitsu is an automatic add to the first-three-episode try-list. If the web manga resonates with you, that doubles the case.
What to watch for in week one: animation density of episode one (premieres usually peak there — does episode two hold?), how the Cypic team handles the first big set piece, and whether the OP/ED give the show a sonic identity beyond the source's existing fan signaling.
Slot it for the first three episodes. If the production's holding by week three, you've got a season-runner.
