Just finished Daredevil and I have to say that it's everything a superhero TV show should be. Gritty, explicit, action packed, realistic, and still fits in the MCU.
Charlie Cox is the perfect Daredevil. A bit skinny, but that could always be fixed with a couple more weights.
Foggy has a good sense of humor so I don't mind him sticking around.
Karen is always nice to look at and is out there representing tall women so I definitely don't mind seeing her again for next season.
Wilson Fisk is PERFECT. The look, especially when he's pounding Daredevil to the ground mid-season, looks exactly like he does in the comics. I only hope that when he does get out of prison he stops being an emotional wreck and gets everyone back to fearing him.
For the future I hope to see more brilliant East Eggs, cross-overs (maybe even a Spidey crossover?), a romance between Matt and Karen, and the inclusion of Elektra and Bullseye.
