Corrected entry: When Bullseye stabs Elektra, we can see that the sai enters upwards through her stomach and the protrudes through her upper back (as is seen by the stretching of her outfit). However, when he throws her down onto the next building, as she's rolling around, we can see an exit wound (a small bloody hole) in the small of her back, between where her shirt and pants don't cover up her back.
Corrected entry: When Bullseye kills Elektra's father with Daredevil's staff, we see Daredevil jumping to grab the staff. There's an explosion, and we see echoes of the staff in Daredevil's 'vision'. We then see the scene from the opposite angle, as anyone else would see it, and it's obvious that Daredevil would miss the staff, even without the echoes.
Corrected entry: Why does Matt Murdock carry the identical baton he uses as Daredevil? With it's bright red handle and gold insignia wouldn't it make more sense to have two different styles, even if he wants both to be able to do the same thing? That's how Ben Urich figured out who he was. That's kind of like Batman using his utility belt to hold his jeans up.
Corrected entry: When young Matt first discovers his powers, he strikes a guy wire and proceeds to slide down. You can see the restraining wire holding him up. (00:12:10)
Corrected entry: In the shot of Electra before they take off their jackets in the playground, Electra's eyes are not green. They're blue. (00:34:55)
Corrected entry: When Daredevil is confronting Quesada in the subway, he's hurt by the sound of a passing train. Considering what they've shown us of his hearing ability, why did he not hear the train coming until it was right next to him? Logic would suggest that he would have heard it quite a while before it got there.
Corrected entry: In the final shot where Daredevil jumps off a high building, he shoots his grappling hook upwards. Why would he hook himself back up from where he jumped off? It doesn't make sense. If he were merely doing it to swing somewhere else the angle of his rope would not likely give him any leverage.
Corrected entry: Although Daredevil can hear bullets loading into chambers and the triggers of weapons being pulled, he still wouldn't be able to move Bullseye's hands into the path of the sniper bullet since he would have no idea where the bullet was headed. He could have been moving into the bullet's path for all he knew.
