10. Inject Moments of Tension
This film will probably be a direct continuation of Infinity War so I would imagine that stakes would be at an all-time high. The world could be in danger and the characters we love could possibly die. Those are huge issues to deal with and the hope is that it takes itself seriously. Humor is great, but it should be used intelligently and not be used as a major crutch or an easy thing to fall back on. It needs to be thought out and the tension must be palpable. Drama is the key component to such a Universe altering film.
