The Dark Knight Returns the most influential Batman story ever written, the Frank Miller master stroke is one of my favorite bits of storytelling ever, character development at its finest. This adaptation tries it's best to stay faithful the the source material while keeping a PG-13 rating and that was a mistake an adaptation demands a commitment to the material. Small changes shift the meaning and power of scenes completely, the knife wielding thugs Bruce Wayne encounters in crime alley for instance, in the book they back off and lose interest when they realize he's going to defend himself, he's not a victim and therefore it would be boring killing him so they head to the arcade instead, in the movie there just scared of him they lose the implication of just how bad these kids are. The worst offenses are the cheap attempt to add more action to the story by making the fight with Superman an actual fight, it wasn't in the book it couldn't be and not using narration losing the best parts of the book honestly. But harping on the fact that it doesn't live up and in some places doesn't respect the material doesn't change the fact that it is entertaining, has a great 80s synth soundtrack, it bring's the amazing visuals to life, and has mostly solid performances (I'm not sold on the Joker) while I can recommend it honestly if you've never read the book pick up the trade on amazon or at your local book store for the same price.
