How an audience reacts to a film or performance all depends on how well it was produced, and the quality of the actors involved. When it comes down to it, the overall quality of any performance is dependant on how well the performers act, how they set the tone, their use of emotions, their gestures, etc. Every single small detail help play a part in the making of any act. And if the actors fail to fulfil their duties as performers, then the whole show will be ruined, and the audience will either be un impressed, or non existent.
it all depends on the film, if the film was good then the audience will love and the film will make lots of money, and if it doesn't then the movie flops.
You have to think about an emotion or feeling first then choose an art style for example if you choose an emotion such as happy you could draw something that makes you happy.
A photographer might be interested in capturing the human element because taking a picture of an actual human may be more natural then taking a picture of something else. I also think that since humans do things all the time that are interesting it makes sense if you would want to capture it.
