Agreed with above.
Here are some scattered thoughts after finishing Season 3, which I thought was great.
Mentioned above, but Bullseye was wearing armor that was cut-resistant and bulletproof in certain areas. Matt had the equivalent of a bed sheet, in comparison. Also, for my headcanon, Dex is also a psychopath, so he may treat pain differently than the rest of us do.
Speaking of Bullseye, holy cow was that first showdown a good one. I could rant about what makes a good superhero action sequence for hours, but I felt like that scene checked all the right boxes. What you want is characters doing things that only they can do, in an environment that showcases them best. So having Dex chuck scissors around with deadly accurate is 100% a Bullseye thing, and something that only he can do. He's also the perfect foil in that scene for Daredevil's radar senses, like when he ricochets a baton off the ground or a baseball off a wall. Aside from Bullseye and maybe Hawkeye, you'll never see a fight quite like that again. Good stuff.
So, I agree that Matt had the advantage in hand-to-hand, but between the suit and the ranged accuracy, Bullseye was able to fend Matt off and eventually knock him out this time.
Speaking of Bullseye, it may have been mentioned above but the point of that final scene (and that's two extremely cheesy final scenes in a row, with Iron Fist season 2) was to show that Dex is still alive, and presumably he's going to be full Bullseye going forward. Hopefully that means assassin-for-hire, black suit, Daredevil's nemesis kind of thing. I'm in.
Regarding fight choreography in general, I thought that this season was very solid. It made sense that Matt was more of a brawler than before. Early on it was because he was recovering, but even late in the game, he was operating with tunnel vision. His master plan in the final episode is "break in, kill Fisk." No time for finesse, this was a desperate man.
Regarding Karen, I didn't have a problem with her at all. I liked that she and Foggy had their own stories, instead of waiting around for Matt, waiting to be saved or not knowing what to do without Matt. There was still some of that - it's called Daredevil, after all - but I liked that all 3 characters had their own approaches. Karen went for the press / public opinion / coercion method, Foggy went for the political pressure / legal system method, and Matt went full vigilante. And none of those methods ended up working. All it took in the end was one good man taking a stand, even though it'd cost him everything.
Speaking of that one good man, if I had one "issue" with this season, it was with Ray Nadeem. It certainly made sense to have him as a character, because we really needed to see how things were going inside the FBI / law. But I thought he was pretty boring overall. The actor has one facial expression. You pretty much knew what he was going to do in each dramatic moment. He wasn't terrible, but he was probably the least interesting link.
Overall, I was quite pleased. I think this was a top-tier Netflix MCU season for sure.
