So what, a descendant of Windu?
Or a new force Sensitive. It's not like he's super strong in the Force, there's no reason he needs a force lineage. It's not like all Jedi are descended from one force sensitive person. Especially since some aren't even human.
Do General Grievous and Han not count? Where was the precedence set that one would instantly dismember oneself while handling a lightsaber? I don't read the books, so I'm asking in earnest. In any case, my point wasn't solely resting on him being beaten, but he also didn't display the reflexes, speed, and precognitive abilities that someone in tune with the Force typically displays. I think an important distinction between Finn being soundly beaten and the Jedi/Force manipulators from previous films is that they also displayed those signature traits. Finn didn't appear to, from my point of view, but perhaps I missed something. Using the weapon of a Jedi is one thing, but using it in the manner a Jedi does is another matter entirely. Yes, I understand that he isn't formally trained, but every other time we've been introduced to a Force-sensitive character who is similarly untrained, their connection to the Force typically gives them a leg up due to the aforementioned characteristics.
These two observations aren't what I'd call "big hints" myself. Still seems like a couple of very thin correlations, IMO.
I don't appreciate the condescension, by the way. Because I don't interpret this movie the same way that you do doesn't mean that I need things spelled out. It's not as abundantly clear as you're insisting it is. I'd like to clarify that I'm not saying that Finn definitely isn't Force-sensitive, I simply don't believe he is based on what I've observed. I'm entirely open to the possibility that I'm wrong.
Okay, condescension aside. From your point of view, what was happening when a newbie Stormtrooper with nothing but a lightsaber loss under his belt started landing hits, with a lightsaber on Kylo Ren, a well trained Force Sensitive saber-master? Did you think it was bad writing? Did you think Finn was just lucky? How did you process that?
For me, once three thin coincidences pop up in a film, knowing that the movie has been made with care, I don't look at them as coincidences, but as part of the story. Now certainly Han and Greivous' use of Lightsabers as blowtorches and sawblades is notable, but none of them started sword fighting like a Jedi does, which is what Finn did, which is a really hard thing to take as coincidence. By itself could possibly be something new in the Star Wars canon, but with all the otherwise unrelated thin correlations that only have one common denominator - force sensitivity - I don't choose to hold out for more information about what all these things associated with force sensitivity might really mean. Why would you?
Next question: Do you perceive Finn as slower and less Precognitive than Luke in Episodes 4 or 5? Why is that? When I look at these scenes, Finn is objectively faster and reacts to faster attacks and fares much better in his battle. Is your perception different? Do you care about the actual speed involved, or is it more about if it felt fast to you?
Condescension back: You actually tried to imply that fighting with a saber is something anyone can do, but shooting with a gun is an indication of non force sensitives. And your follow up is Han and Grievous as though what Finn did is more similar to using a blowtorch or spinning his arms than fighting a Sith apprentice like every other Force Sensitive. That's a hard deep yoga-worthy logical stretch. You gotta own that.
They only setting themselves for dissapointment.
Finn represented his saber skills well, landing hits on a Sith apprentice and implied some precognition, knowing stuff he couldn't just know. I wasn't disappointed, and even if they explain his instant saber skills and clairvoyance as something other than force sensitiveness, I won't be disappoitned, because then he'll be a non force sensitive that is so badass he can go toe to toe with precogs even though he has no training whatsoever. Once he has training, geez. Jedi don't stand a chance against his super-luck powers that don't come from the force.
