WatchWise Score
62/100
★★★☆☆
Provisional — few votes so far
Blended from TMDB 66 (100% weight); shrunk toward a 62 baseline by 251 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.
- · Middling scores: fine for a casual watch, not a must-see.
- · Short and done in under an hour and a half.
