This version, or the remake?
Same old boring question, but Hitchcock himself said -
"the first is the work of a talented amateur and the second was made by a professional.”
They each have their own place though, they both have the things a good film needs - suspense, strong characters (some horribly nasty, some immediately nice), action, music, fights, guns, exotic locations, laughs...you guessed!...
It's a...
THRILLER...
And Hitchcock invented it...
