The big difference is this film has the main character using the force more than did in that film.
Luke spends half the movie talking about what a great pilot he is. He plays with a model of some sort of plane, and if you pay attention, you can see a full-sized one parked in a garage behind him. And everyone goes on about how his dad was a pilot, suggesting that he has natural ability.
Then when he's on the way to Alderan, Kenobi teaches him how to use the force to help him aim at things.
At the briefing before the attack on the death star, Luke is the one who seems to think it's doable since he's been...shooting large animals for fun... back at home. And it's not like it's even that difficult to imagine him doing it since he's just trying to hit a target that's more than six feet across.
ETA: compare that to this stupid movie, where Poe (while in the middle of a dogfight where he downs about a dozen enemies over as many seconds) is able to shoot a person with his x-wing, without hitting another person standing right next to him.
