Jacen and Jaina Solo, Ben Skywalker, Corran and Mirax and Valin Horn, Iella Wessiri Antilles, and Tycho and Winter Celchu will forever be better names than Rey and Kylo and Finn and Poe. No question in my mind.
And while I actually really liked Daisey Ridley's portrayal of the character Rey, it would have been a lot better if they'd just named the character Jaina. I mean, that's the character she's playing, pretty much. Same attitude, same abilities, same no-nonsense, I'm-not-a-damsel-in-distress incredibleness. Just a crappy story instead of something really good. And they could have done something really good - it's not like they didn't have the material for it.
*shrugs* Oh well. It's water under the bridge at this point. I still keep my headcanon.
And yes, the concept of Star Wars is awesome. Lucas had a good concept. Of course, he then had to go butcher it, and Disney skinned it and hung the carcass out to dry...
