Wanted. It’s a completely different story, in the movie it’s about a loser guy discovering destiny murders that are ordered to kill people by a Loom. The comic is about a loser guy discovering a secret society of super-villans because he also has a superpower.

But I would also like to present a counter-example. Watchmen, the ending is different from the comic to the movie, and I much prefer the movie ending. In the comic the plan by the villain is to make an alien-like monster appear out of thin air, because this will make humankind unite, in the movie his plan is to blow out the major cities in the world and make it look like Dr. Manhattan did it because then humanity will unite both out of fear and trying to stop Dr. Manhattan from doing it again. I never questioned the comic, but after watching the movie I got the nagging thought of “why would an alien appearing unite mankind? They don’t know if the alien destroying stuff was purposeful, them thinking Dr. Manhattan did it is better because they know it was intentional and done by someone who knows who they are”
