The ability of a film to entertain its audience is the product of a number of factors.
Film, like paintings and novels, is a form of art. How one responds to that art is entirely dependent upon the personal tastes of each individual viewing or reading the item in question. Not surprisingly, whether a film, novel, or painting is "good" is entirely a subjective matter. We each have our own opinion of what we like and dislike.
In the specific case of film, which more than the other forms of art can manipulate the emotions of the audience, the people making the film strive to accomplish goals consistent with the underlying story line. In short, what makes a film entertaining is how it captures the audience's attention. If the film is a comedy, it's entertainment value can be measured in terms of the how much the audience laughs. If the film is suspenseful, the filmmakers hope that it captures the attention of the audience and makes it nervous, frightened or angry. So-called slasher films respond to the desire on the part of many film-goers for violence and bloodshed, usually at the expense of people who "had it coming."
What makes a film entertaining is whether it accomplishes its objective. If audience members exit the theater humming or singing a song from a musical, that film probably succeeded at entertaining. If they exit the theater discussing the identity of a murderer, the "who dunnit" succeeded in capturing and holding the audience's attention. If you liked the film, then it was entertaining.
It really depends on whoever is watching the movie. We all have different interests and dislikes that come across from watching different movies that you begin to notice yourself picking one genre over another because of the movie's plot, the acting of a character, or dialogue. I personally love watching comedy's with a refreshing and modern sense of humor, rather than what I consider cliché.
This varies for different people
Romance and good acting may be very important for some people while some people focus on the plot and the main character development. Music and timing and scenery etc.. may also be another factor.
It all depends on what you plan to watch. For some it could be the plot or their favorite characters or even the level of thrill for others. There has to be a good script and actors though because if you cast a terrible actor in an amazing script or vice versa it will completely fail
A good plot, a good actors makes the movie entertaining. The plot has to be interesting to make audience to watch this movie.
