• Meaningful character development (not necessarily advancement, but at least exploration)
• Motivated decisions made by at least two people in the story: the protagonist and the antagonist (or just the protagonist if it’s a PvE-type movie)
• A challenge that challenges the protagonist(s)
• Dialogue that sounds at least plausibly like human speech
• Reactions that seem at least plausibly like human reactions

A plot that doesn’t have many holes is a nice bonus, but as long as everything else is present, not a deal-breaker.
