There was no real comic book spectacle in any of the action. No real cinematic action set pieces.
DD got beat too easily and too often.
The excessive violence (and to an extent) profanity was off putting some of the time.
Way too many long conversations. Some that could've been edited as to improve the pace and a few that could've been whacked all together.
The costume really should've came in earlier. There's really no excuse for them holding out so long in this day and age.
Only ONE token shot of his Radar Sense.
No real supervillians to speak of. We got Red Ninja guy,but that's about it.
A lot of my problems can be summed up in their mindset of "Telling,not showing". We don't get to see Matt save the guy that resulted in his blindness,only the aftermath. We don't actually see Battlin' Jack Box in the ring,only the aftermath. The aforementioned lack of radar sense.Even the action was affected by this many times. For example in the last episode where the camera focuses on the crooked cop's face instead of actually letting us see DD in action. (I mean the show is called "Daredevil" right? I'm not wrong for actually wanting to see him in action,right?) I don't know if it's a product of their minimalist framework for the show or working with a TV budget,but they certainly didn't rise above TV's limitations.
I really don't see why people have looked past some of these seemingly obvious flaws. Perhaps once the bloom is off the rose. But, I found most of the show fairly underwhelming.
