It's the Pied Piper, Charlie Brown (2000)

The Radar read

A quieter title still finding its audience, though the rating rests on a thin sample, so treat it as provisional.

Synopsis

Based on the legend of the Pied Piper, it stars Snoopy as the title character, who tries to rid the Peanuts' gang's hometown of mice by playing his concertina, in return for a year's supply of dog food.

Radar blends quality, momentum and freshness into one “what to watch now” number — so a great older film can sit lower than a rising new release. The Quality signal above is the time-neutral rating, which is why an acclaimed classic keeps a high quality score even when its Radar number is lower. Radar outputs are editorial algorithmic recommendations, not objective facts, and may change as signals update. A Radar score is not the same as a TMDB, IMDb or critic rating.
