Comedy classic that holds up perfectly, thanks to two outstanding lead performances along with a sharp satire on class & crony capitalism. Murphy & Aykroyd are at their career best, bouncing between super rich & miserably poor effortlessly. Aykroyd particularly shines as his life slowly falls apart, and even when it gets pretty dark, you can't help but laugh. Both leads get great support from the rest of the cast, particularly Jamie Lee Curtis as the hooker with the heart of gold and both Ralph Bellamy & Don Ameche are perfect scumbags. Behind the camera, John Landis makes a pointed satire on class & crony capitalism and how those ahead rig the game to stay that way, while not being an condemnation of the getting rich in general (that's what the heroes ultimately do). Even the ridiculous parts work, some resulting in the film's biggest laughs (the gorilla sequence is laugh out loud funny). Overall, one of the funniest comedies ever and, since it takes place during Christmas, a great holiday film.
