How do you feel about movie adaptations of video games, anime, comics or books?

Anime and video game movies are almost always misses and are notorious for pissing off die hard fans (Dragon Ball Evolution, the last airbender, mortal kombat, street fighter), the only movie adaptation that I can think of that is actually good is Detective Pikachu. Sonic hasn't even come out yet and fans are already complaining about it. But books and comics for the most part have been pretty good in their movie adaptations with films ranging from all genres like Harry Potter, Jaws, Moneyball, The Outsiders, numerous super hero films, etc.
