WatchWise Score
65/100
★★★½☆
Provisional — few votes so far
Blended from TMDB 85 (100% weight); shrunk toward a 62 baseline by 336 total votes. Provisional — few votes so far. Not a plain average: sources are weighted by reliability and vote count, and thin evidence is pulled toward the catalogue baseline.
- · Rated by only a few hundred people, so the score is less reliable.
