The best film directors are master manipulators who can magically transform an entire theater audience into a group of happy to sappy sapient lemmings or wide-eyed marionettes easily controlled from start to end credits. Their best films have the masses cheering the heroes, hissing at the bad ones, empathizing with the downtrodden and generally feeling whatever emotion a scene calls for. Yes, there are exceptions to this non-rule (too-likeable villains, swapping out all attempts at sympathy for more explosions and eyeball rolling plot twists you can see coming 20 minutes before they occur). But when you get right down to it, you know your cinematic needs are being taken care of when certain directors are at the helm.
Or, as an old friend once said:
In other words, this is a Spielberg film, folks.
