Why do a lot of movies with sequels nearly always seem to follow this way?

Question

#4 is always bad writen

Examples:

Goblet of Fire (unlike its other movies it hardly even covered the book, and what it did cover was...... poorly done)

The Chamber (I have read every John Grisham novel out there, and i was looking forward to this movie. Again same problem.. it barely covers the book and poorly done in that)

Spiderman: 1 was great 3 was greatest 2 was... ok... so they did a great, ok, greatest.

why do movie series do this?

Harry Potter 5 (despite what most people willl say at least covered the book a lot more then Goblet did.

Answer 1

Why do people want the movie to be the same as the book.
Just take it for what it is, a good book or a good movie.
Who cares if they are the same or not.

Answer 2

Very simple.

JK Rowling wrote a rich and complex story used thousands of printed pages to tell it.

Movie-makers know that audiences start getting restless after just a couple of hours of sitting in a movie theater. They cannot possibly faithfully reproduce every single subplot and side-story of a 700 page novel, while keeping a focused, understandable, and entertaining product.

Sometimes, a screenwriter or director, (or both) have a different understanding of the focus of a story, or a unique idea of how to tell it. Some simply want to change a story enough to put their own personal spin on it.

People are imperfect creatures. We get the best product people Can produce.

Answer 3

Books those were'nt written supposed to film when written. falls into this category.
