Your second sentence contradicts your first. How can you say that we nearly never get to see Matt act like a lawyer and then say that in season 1, Matt's lawyer abilities are just as important as his punching abilities to bringing down Fisk? You can't have it both ways. And isn't it good that Matt doesn't try bringing down Fisk the same way he did in season 1? Wouldn't that just be repetitive?
[sigh] What I meant was, in season 1, Matt's lawyering was as essential to bringing down Fisk as what he was doing as Daredevil. But ever since 2x04 and Elektra showed up, Matt's leaned too much into his Daredevil side and not been able to find a balance between his two lives. Plus, Charlie Cox had said something on the pre-Defenders cons about "Lessons Matt learns in The Defenders will carry over into DDS3" and one of those, I'd hoped, would be the importance of allies, rather than turn up the "Lone Hero Who Must Work Alone" crap.
At least, I'd have been happy with a Matt+Karen teamup starting early on, maybe starting in episode 3 when she showed up in the courtyard at the hotel.
Plus, I'm gonna be honest, if we had more of Matt being a lawyer in season 3, we could have had things that resolved some other plot points. Like, whatever happened to Stewart Finney and the Hispanic brothers that Fisk hired as muscle while he was in prison during season 2? Another one is that I really wish Matt had done more to help Melvin after Melvin got arrested, and that could've been an interesting subplot of Matt trying to defend Melvin while also trying to keep Melvin from learning that he's Daredevil, and ultimately failing at that. (Unless the writers intentionally left the Melvin thread unresolved so they could set him up to be the full-on Gladiator in season 4, if season 4 ever happens. I'd love to see Matt eventually get the red suit back.)
Speaking of unresolved plot points and secret identity shenangians, Fisk figuring out Matt is Daredevil. We know Fisk saw Matt fight in the prison but I don't think there was ever that 'Eureka' moment. I mean...it was all confirmed when he got Matt's medical records from Donovan, and spoke to Karen, but it was more of this slow "connecting of the dots" sort of situation. We never really saw him react to it. I think we really should have gotten that kind of reaction. Like, if we had a scene of Fisk watching that fight over the security cameras, and having that moment of realization, it could've gone somewhere very interesting. Then Fisk getting Matt's medical records, and maybe a scene of him obsessively trying to figure out how is a blind man capable of doing that? Then looking through any and all footage, any and all evidence, of him as Daredevil, kinda like we saw him doing with Dex's records. Does Fisk think Matt's faking being blind somehow? When he says Matt's name to Nadeem, does he have a plan beyond 'let's ruin his day even more than I already have?' Because getting the FBI to catch Matt for him is pretty smart but, also, does it change his endgame? And did he really think the FBI would be able to catch him?
Hell, I'd have been all for a season 2 style confrontation between Matt in his unmasked lawyer mode, and Fisk. It wouldn't be repetitive, because Matt no longer having to pretend to not be able to fight back would certainly change his approach to the situation. Or, at least, how he'd talk to Fisk.
'Cause when Matt unmasks himself in that final fight, is Fisk looking at him like 'he's actually blind??' and internally having this burning need to understand and dissect everything to do with this unprecedented situation because he does not like new variables in his universe? Secret identity tropes are very rampant in Daredevil (in a good way), and this was one of the most pivotal identity reveal moments in the show. I feel it got short-changed a bit.
