Yeah, I absolutely include the original trilogy in my critique of overuse of deus ex machina. I don't think tradition is a good enough excuse for continuing to overuse the same tired plot device. Just because your weird uncle has a tradition of getting blackout drunk at family get togethers and passing out in a puddle of his own puke doesn't make it alraght that he keeps passing out in a puddle of his own puke.
The new series has it's own faults, namely giving us one of the worst protagonists ever. I probably don't need to go over how Rey is a Mary Sue, and Luke was kind of a Mary Sue also, but at least he had to struggle. He sucked with the light saber at first. He got his ass handed to him by his pops the first time the fought, etc Rey is instantly the best at everything. Never held a light saber before... 5 minutes later she's the greatest swordswoman on the battlefield. She thwarts off the powers of a sith who has been training his whole life with zero force training. She hops into the Millennium Falcon turret, having never fired one before and is instantly the best gunner in the galaxy.
The goal of having a strong female protagonist for girls to look up to is an admirable one, but in the process the writers went waaaaaaaaaaaaaay overboard and robbed Rey of the very thing that makes us cheer for the protagonist, them being the underdog, failing, getting defeated, then dusting themselves off and finally triumphing. Rey can never be the underdog because she is perfect and the best at everything from the start. Where's the struggle?
