Thanks to online ratings, discovering whether a movie is worth your time has never been easier. A simple Google search surfaces countless sites sharing opinions on the latest releases.
The three most trusted are IMDb, Rotten Tomatoes, and Metacritic. But how do they differ, and which one delivers the most reliable insights? As someone who's analyzed countless films and their aggregated scores over years of reviewing, here's a clear breakdown.

Metacritic's letter-grade conversion raises questions. Assigning an A 100% makes sense, but a B- at 67% feels harsh—most grading scales place 67% near a D or F, not a B-. An F at 0% also seems overly punitive; 20-30% might better reflect minimal merit. With varying scales across sources, these conversions can distort critics' true intent.
Unlike Rotten Tomatoes' transparent critic aggregation, Metacritic offers limited details on review sourcing, potentially undermining score credibility.
No single site rules them all, but each excels in specific ways based on proven strengths:
Cross-reference all three to align with your tastes over time.
Scores aren't gospel. They undervalue "so bad it's good" cult favorites or clash with individual preferences. No aggregate captures every viewpoint perfectly—trust these tools as starting points, but follow your instincts.
