Probably harder for you because you came in with expectations for Finn.
I came in with no expectations at all. Was curious about the movie and that's it.
The way Finn was portrayed sits well with me. I really like the guy lol.
You're probaably right
If they didn't bait and swithc me with the marketing making you think Finn is a Jedi I would be as heated as I am now. because I right now I'm angry. (fanboy anger not real anger)
I took my 10 year old cousins, 1 boy 1 girl, I asked them who their favorite characters was, what'd they say.
GIRL: REY!!
BOY: ....thinks....thinks...Probabaly Han Solo or BB-8
niether said Finn.
Honestly the I think 90% of the reason people like Finn more than logic dicates they should is becuase of Jon Boyega's inherent likability, charisma as an actor, I think that Kid is a movie star and I have since attack the block, becuase imo Finn isn't a great character it's saved by Boyega.
