A question for comic book fans.

Rating: 7/10 (1 June 2016)

This isn't a review of X-Men Apocalypse (a movie I enjoyed, as my rating indicates). Rather it's a question-- an observation, really-- about the genre.
Screenplays are based on original ideas, or they're adapted from another source, such as a book, a fairy tale, a play, a TV show, etc. Comic books have recently become a gold mine for adapted screenplays, but the genre isn't new. In 1931, the movie "Skippy" was based on a comic strip, and the screenplay was nominated for an Oscar. Two more nominations came in 2003, for "American Splendor" and "Our Cancer Year," both based those respective comic book series.
Most moviegoers understand that adapting a film from a book or another source means a departure from the original material. Film, after all, is a different medium with different demands on creativity, including whole armies of creative collaborators led by the director and writer(s).
But fans of Marvel and DC Comics don't seem to understand that when they enter the movie theater, they're going to see a movie, not a comic book come to life. Many reviews posted here seem to be looking for absolute faithfulness to the original material, which is not only unrealistic (film has different tools), it is an insult to the creative filmmakers who adapt the material.
I've seen all the X-Men movies, and the various Avengers films, and Superman and Batman, and etc.-- I'm a genuine fan of the genre. But I have read none of the comics. Not one. I was a film student, and learned to appreciate that medium on its own terms. My favorite novel is "Moby Dick," but nobody needs to read Melville's masterpiece to know that the movies based on it are mediocre. Nor does anyone have to read "Moneyball" or "The Martian" or "Do Androids Dream of Electric Sheep?" or "The Maltese Falcon" or "Rebecca" to know the film adaptions are good.
Films must be judged on their own merits, not on how closely they adhere to the original source material. If comic book fans come to terms with that, they may find themselves enjoying the original as well as the adaptation.
