Spider-Man 2 (Widescreen Special Edition) (2004) for $2.71

More than a few critics hailed Spider-Man 2 as "the best superhero movie ever," and there's no compelling reason to argue--thanks to a bigger budget, better special effects, and a dynamic, character-driven plot, it's a notch above Spider-Man in terms of emotional depth and rich comic-book sensibility. Ordinary People Oscar-winner Alvin Sargent received screenplay credit, and celebrated author and comic-book expert Michael Chabon worked on the story, but it's director Sam Raimi's affinity for the material that brings Spidey 2 to vivid life.
