Casino - the portrayal of Robert DeNiro and Sharon Stones relationship in that movie is just remarkable. its compelling and uncomfortable to see, like watching a really detailed, super slomo, very traumatic car crash happening. throws more love, power, lust, addiction, betrayal and whole host of other stuff into the "romantic interest" part of the movie than the rest of hollywood could even imagine. stunning performances from both (plus Scorsese and whoever wrote it)
