It was difficult to describe... I've always read the graphic novel slowly, deliberately, soaking in every panel, every meticulous detail woven in. As a film, even a 2+ hour one, the audience obviously doesn't have that luxury. The film goes through as much important character backstory as it can, as quickly as it can. Can see how the average movie-goer would be overwhelmed, but can't speak for them. Can only speak as a reader. Was faithful. Honestly, more faithful than expected. PETA-unfriendly moments preserved in all their warm, bloody detail. Rorschach's dialogue not as sanitized as trailer might lead to believe. Whores and politicans and liberals and child pornographers, not just "the world". Changed ending was better executed than expected. Unified main plot with Jon's character arc neatly and effectively. Still, as die-hard fan of the novel, left wanting more. Possibly prefer director's cut?
Must remember to investigate further.
