Klumpen0815: Is there any movie adaptation that even tries to stay as close to the book as possible?
Since directors are mostly eccentrics who don't like to be told what to do, this seems to be impossible.
While not a proper book, the movie adaptation of the comic book miniseries
The Watchmen was an incredibly faithful adaptation of the source material. Sure, people have complained that
the catalyst for the ending was modified, but the
ending itself is still the same. Aside from a bit of the meta-textual stuff, the bulk of the comic is in the movie
(even more so, if you watch the much longer Ultimate Cut). So many of the scenes and much of the dialogue is pulled straight from the comic that someone who had never seen it before could mouth along to certain parts just by knowing the comic book well enough. It is, to me, the closest adaptation of a story that I've seen.
While you claim that most directors are eccentric, there are definitely some that are not. As our generation gets older and starts taking over for the "old guards" in Hollywood, this will change. People like James Gunn, Joss Whedon Guillermo del Toro and J.J. Abrams are changing how movies are conceptualized, produced and presented. Films like Guardians of the Galaxy, The Avengers, Pacific Rim and
(potentially) Star Wars: Episode VII are proving that you can create something on a grand scale that is still, at its core, a movie that you just made for yourself. The old way was to make movies for the masses; movies that you "knew" people wanted to see. The new way is much more genuine; make the movie you always wanted to see and, chances are, the masses will also want to see it.
There will always be movies that pander to the masses and eccentric directors who will bastardize a classic piece of literature or pop-culture, but I think that those films are starting to fall out of fashion. There may never come a day where they become the minority, but we are definitely seeing a change in the tides of the sea of cinema these days.
TL;DR - The Watchmen is a great movie. Tekkaman-James doesn't know how to stop talking.
