Point being, Rey is skilled at almost everything, but with no training in anything! The problem lies with two people, Abrams & Johnson.
To truly write a SW movie takes years and years to develop. Lucas had decades and more to figure out his story and overall vision. You can't just put this together within a year and a half and expect it to be great!
Countless hours has to be invested in this for it to succeed. Now if J.J. took 3 years, just get the story right for TFA, he'd probably would have created a classic! True quality comes with time, but I guess Disney/Lucasfilm has no idea of this!
Having taken a lot of time to study writing and story building, I'm gonna say this is not precisely true. A dedicated writer doesn't necessarily need years to craft a tight story, certainly not a screenplay. This is hugely dependent on the writer, on a case by case basis.
All that aside, the "Rey is awesome with no training" argument just doesn't hold water.
If we're going to compare her to Luke then we should do so fairly.
She's lived on her own for years on Jakku, where she clearly learned how to fight and survive on her own. As of the beginning of TFA she's already a bigger badass than Luke was at the start of ANH because of this. At the end of that film she fights a powerful but mentally unhinged Kylo Ren and bests him by giving in to the force though only having learned of it recently. You'll note that we see her actually kicking a few ruffians asses on Jakku prior to this. It's established that she knows how to fight already.
We never see Luke do anything pilot-wise in ANH, except drive his busted old landspeeder in search of R2, though he brags a good game in front of Han at the cantina ("I'm not such a bad pilot myself! We don't have to sit here and listen to this") and during the planning prior to the Death Star attack, where he mentions flying the T-16 and bullseyeing womp rats.
Then he gets in an X-Wing and even though he's just learned about the force that day or the day prior, he successfully tunes in to it enough to fly down the trench at 1000's of kph and nail the target perfectly.
If we go down this line of reasoning then it seems blatantly clear to me that we're all a bunch of ******* nerds. Wait, I mean it seems blatantly clear to me that Rey's situation parallels Luke's so closely specifically to assuage these kinds of "She's too good at stuff" arguments.
Which then cues the folks who bitch about the movie being a complete retread of ANH and then I throw my hands in the air and walk away for a bit to catch my breath.
