It does get better, yeah I felt the same way about eye sight it was the first thought that came into my head! we are so lucky alhamdulilah.
It's the most critically acclaimed super hero tv show thus far, you just have to see the reviews around the net for yourself 96% on rotten tomatoes. You should watch the entire season.
It's the complete opposite to Arrow and Flash in that it's not your conventional super hero tv series, it's very dark and gritty. Also does the DareDevil character justice which is the most compelling imo in comic books for me, they just haven't done him justice until now he has so many dynamics in terms of his psyche, his struggles, religion etc and he isn't the type of character that always wins in the end like a spiderman etc but never gives up.
I said this earlier in the thread that sums up the show:
" He's probably the most unconventional comic book character from the Marvel Universe given his dark and gritty nature. The show has been fantastic, it's not your typical goofy super hero series nor anything like Arrow which is great beyond the filler content. It's a very realistic Crime Thriller having watched the first two episodes. The tone of the series is very gloomy and intense with a focus on salvation and sin with the usual evils which plague hell's kitchen (name of the city), Poverty, crime and drugs.
Also, Daredevils superpowers have not been exaggerated you'd think he doesn't really have any and many a time his opponents get in quiet a bit of offence on him. This adds more realism during the fight sequences making him more of a vigilante assassin in a way, there is a little focus at times in short moments on his four senses which have been been elevated after losing his eye sight during fights. The choreography of the action has been great and production top notch"
