7 hours ago, Albertese said:"Cheese" may not be the right word. But Star Wars was always meant to be mythic and operatic. Luke for instance, who barely reacts to the death of his family but is broken up by Ben's death. Then once they arrive at Yavin the Rebels plop him into one of their fighter jets on little more than Biggs enthusiasm. Not exactly realistic.
I'm with Derrault - there's a big difference between knowing the uncle you've been at loggerheads with is probably dead and getting it confirmed after a drive of some length, and seeing the person who's been acting as a father figure and mentor get cut down in front of your eyes. As far as him flying, we don't see everything that happens between their arrival at Yavin IV and the ships taking off...but compare it even to Independence Day. "We have planes, we are definitely going to die if we don't stop the juggernaut coming for us, so anyone who assures us they can fly a plane gets one." What do they have to lose by giving him an X-Wing that no one else was using? The Death Star is blowing them up anyway. Works for me within the normal level of suspension of disbelief I have for movies.
Even if you want to think those events are not completely realistic or logical, I don't see that they compare to the completely unbelievable-from-a-human "Noooo!"
