I watched the entire season in a span of a few days, this was one of the few Marvel characters (major heroes) I knew very little to nothing about except for a few certain things such as character name, power, and race, about this character. Now I first thought it was a bit slow at first and the origin story bothered me a bit as it seemed too much like a DC comic's male hero, Rich kid, parents died, and received an absurd amount of training.
But overall after all was said and done I loved the series, yes they could have definitely choreographed the fights alot better considering the character is (almost at this point in time) a martial arts expert. But outta the 4 (soon to be 5 netflix marvel heroes ) I would have to say he is a strong second favorite almost top favorite.
Now the thing that pissed me off about some of the negative reviews was that critics were saying that the "white-washed" the Iron Fist main character Danny Rand, saying that he should have been Asian, now that would have actually ruined it for fans because Danny Rand is not Asian, he in comic lore is what you would have called a spoiled privileged white boy. But yes Finn Jones definitely needs to take up some martial arts training in between seasons and the Defenders seasons to make his fights that much more impressive.
