Same here. The Tarantino film has more cult hoopla, but the Bryan Singer film is just fucking brilliant with iconic quotes and the most memorable criminal mastermind ever: Keyser Soze!
Both great but I prefer Reservoir Dogs. I prefer both to Pulp Fiction, though I also very much like that film too. MTF
Not quite same era, what made reservoir dogs special was how different it was to the mainsteam at the time, leaden episodic stuff like lethal weapon 3, the bodyguard..the way it used music, the stylised dialogue, the editing and nonlinear narrative, you could argue that usual suspects could only have ended up as it was thanks to tarantino's trailblazing. Looking at them now, usual subjects is more re watchable.
