No movie will completely tickle everyone who sees it. There will always be parts that strain credulity or test patience. No film will ever satisfy all who see it, no matter what you do. Still you want to keep people as engaged as possible. There are ways a filmmaker can mitigate parts of their movie that may offend, bore, or take someone out of the film-watching experience.

Suspended Disbelief

A film maker will get a certain amount of leeway from the audience no matter how they feel about you. To start with, nobody quibbles with the unstated camera and microphone that make it possible to record this supposed event. We all agree that this is a fictitious event that is being played back to us as a facsimile of life and not life itself. This works in your favor not only for the basics of the filmmaking conceit, but also can bleed into other areas like an actor's performance that is a little too "up" or the color of a car not making sense for the character that drives it.

Authority

Beyond the base level of rope an audience gives you, more can be gotten when you prove you are an authority on the world portrayed on screen. If you show you are in control of the elements that make up the setting, characters and story, an audience may grant you the benefit of the doubt in other areas. Authority need not be something they like or agree with, more like a stamp that is unique to you as a filmmaker. They may not agree with the types of fabrics you have clothed your characters in, but since it seems to be a style and doesn't stick out with other elements they will likely accept it.

Unique Vision

It's easy to pick apart big budget movies because they are a dime a dozen. If the one that came out this week is stupid, there is always next week. These movies are commodities. Just like anything plentiful, you are more particular about it. Water is available everywhere, but we want bottled water because it tastes better. Clothing is cheap and available everywhere, but we want certain kinds of clothes. When a filmmaker comes with a movie that is nothing like anything seen before, audiences will recognize it as a rarity. If it is at all compelling to them, they will savor the experience. Instead of holding it to the same standard as a bigger movie, they will overlook things in light of the unusual nature of it. Make something that is different and people will give you a break.

Respect

Much of the movie-going public craves respect. They don't want to be talked down to, they want to be challenged. These audience members will reward this respect you show them with leniency. When you give them something they've wanted in a movie for a long time, they will overlook those rough areas that could ruin a lesser movie. Respect could be stories with complex characters, it could be lack of explanation of things the audience should figure out for themselves, or it could be just telling a story that has never been told before.

Saul Bellow said "with a novelist like a surgeon, you have to get the feeling you've fallen into good hands - someone from whom you can accept the anesthetic with confidence." I feel filmmakers need to exude the same qualities. If you do the most on your part to make it a good experience for the audience, they will give back and allow you room to experiment and grow as an artist.
