The Netflix shows are framed similarly to the films. You don't absolutely need to watch all of them, but there's some connective threads and ultimately a payoff once the big crossover event happens. Daredevil, Jessica Jones, Luke Cage, and Iron Fist are leading up to The Defenders. Even so, you can probably get away with skipping everything and just watching The Defenders whenever that comes out. I have yet to see Thor: Dark World and I still feel like I'm up to speed on the MCU. Each movie and show is meant to still be enjoyable individually though you're rewarded as a viewer if you see everything. Luke Cage plays a pretty substantial role in Jessica Jones yet you can likely still skip it and understand Luke Cage's show later this year. Additionally, Marvel hasn't announced any major crossovers to Daredevil like it did with Luke Cage appearing in Jessica Jones so you should be fine.
I would still recommend watching Jessica Jones if only for David Tennant's amazing performance. I didn't enjoy Jessica Jones (the show or character) anywhere near as much as Daredevil. Jumping off of what Evan_B said, I don't even think Kilgrave was that interesting. However, David Tennant was just so good. I'm not even a Dr. Who fan.
