📌 What These Rankings Reveal About 2025 Cinema
1. Franchises Still Rule
Well-established IPs (Avengers, Avatar, Mission Impossible) continue to deliver strong returns, especially when evolving the formula.
2. Streaming vs Theaters
Some expensive films like The Old Guard 2 found more success on Netflix than they would have in cinemas—signaling a shift in how high-budget films are consumed.
3. Original IP Risk
Projects like Atlantis Reborn and Eclipse show the financial risk of betting big on untested universes, especially when lacking buzz or critical praise.
4. International Viewership Matters
Several films (Transformers: Cyberstorm, Horizon) salvaged poor U.S. openings with strong global box office support—especially in Asia and Latin America.
