I think De Palma gets something of an unfair rap. Personally, I don't love any of his movies after Blow Out but I think a fair chunk of his movies are still OK (Body Double, The Untouchables, Raising Cain, Mission: Impossible) and the ones that aren't that great still have something of note in...
Yeah, even if you're shopping at a swanky store (albeit one that needs more secure curtains on its dressing room doors), that's good advice because another person may have tried them on before you.
