Hmmm..
Why is it okay for a guy who has never seen let alone picked up a lightsaber and who (supposedly) is not using the force able to use one so well? Yes, he lost to a highly trained force user, but Finn was pretty darned competent.
And I see complaints of Rey suddenly being such a good pilot, mechanic and force user, yet a guy who has never once sat in a gunner's chair mastered it in mere seconds, taking out a number of ships and saving the day while Poe and Rey both flew the ships. He's a crack shot with a blaster, yes, but knowing how to point and shoot a hand weapon is nothing like mastering a computer targeting system on a moving ship engaged in a dog fight.
Yet somehow Finn is the 'loser' and Rey the 'Mary Sue?' I'm just not seeing it. Yeah, Rey's the force user/Jedi/Skywalker family member (it is the Skywalker family saga after all; one that has been dominated by men for the past six movies)
I really love Finn and didn't think him at all incompetent or stumbling about. He's a powerful character who goes through the most growth in the film, taking control of his own destiny from the get go. He was brainwashed and didn't have a life, so now he gets to go out in the world and learn how to be a real human being and that is fantastic. No, he doesn't know how to fly or how to fix things as they aren't in his wheelhouse, but I just don't see him as being the comic relief or an ineffectual character.
As to understanding how young black men feel, I do...and I don't. As has been listed elsewhere in this discussion, there have been numerous sci-fi/fantasy films with black male leads/co-leads, and Finn is the driving force behind the story in SW VII.
To compare in SW, if it's of any help, we've had four named roles of some import in the series performed by black men - Lando, Mace, Darth (don't care who was actually under the helmet - the voice makes the character) and Finn versus two women (Leia and Rey).
By comparison, as this is a US made movie, black men comprise about 15% of the population versus women who comprise 50%.
So on the one hand, I do fully understand the way black men feel about wanting to see more representation as heroes on the big screen, but on the other hand, it seems there are just as many if not more male black heroes as there are female heroes (again, see previous post about black male leads). Young black men got to see a kickass black male Jedi Master. Where was the kickass woman Jedi master?
And again I point out - three films, 90 seconds of women other than Leia talking
I stand by my opinion that Finn totally rocks and I loved how the entire story was pretty much Finn's story. It started with him and it followed his actions, his choices and his changes that made the movie great, imo.
