Why The Hand dug and protected a 40 story hole inside that building?

I was a little disappointed that Frank didn't get into an epic shootout in the end to assist Matt since that's where it seemed to be heading, but I think they probably wanted to focus more on Matt taking down the Hand than Frank to close out the season. So while I felt a little shortchanged seeing him find the arsenal and don the traditional skull costume, I think it was more to set him up for his own upcoming series.

Fairly obvious that Elektra was going to be resurrected given what we know about the Hand. I'm looking forward to seeing where that storyline goes since it felt a little incomplete with how important the Black Sky was and the harvesting of the blood.

I hadn't been following as much of the production of this season as I did the first, so it was nice to see Fisk and Stick return.

I was able to buy the transition of Page to working for the newspaper, but I think she shot up in the ranks a little too quickly. I liked the idea of her getting Ben's old office, but she just seems to new to the paper to get her own office so quickly.

I really liked that they brought in Carrie-Ann Moss as the one who would be hiring Foggy.

Nobu didn't feel as threatening this season, but that could also just be because of how Matt has progressed in his role as Daredevil. I loved Stick killing him once and for all in the end though.

The whole he can't detect them because he can't hear their heartbeat thing. OK, he can't hear their heartbeats, but he can hear their "weapons" but not if their weapon is their hands/feet. I get their ninjas, but he detects completely inanimate objects all the time, things that literally make no noise at all.

And the breath thing came across as so dumb. So these guys either have no heartbeats, but still need to breath...or they are so well trained they can stop their hearts while having full out fights with DD, but they can't hold their breath. And the fact that DD couldn't hear them breath until he was told to makes no sense either.

Also seems odd that Stick trained DD to fight, to prepare him for war against the Hand, by teaching him methods that work great against everyone but Hand soldiers. I guess maybe the whole no heartbeat thing is a new method they developed because Stick is blind as well?
