Building blocks? More like Legos dumped on the ground.
That's why I don't count the prosecutor storyline as something that's been "playing out" this whole time. There's been absolutely no development of the concept or new status quo. It's preposterous that Matt could juggle the hours and public profile of being an ADA in NYC with being a vigilante, but all the tension that could come from that goes completely unaddressed. It's like he just makes up his own hours, takes a case when he feels like it. That made SENSE when he was a defense attorney, not to mention the depth and complexity that contrast gave his character - busting criminals extrajudiciously by night, giving them a robust legal defense by day. Daredevil as prosecutor is like Spiderman as billionaire or Superman as human wrecking ball - it's a fundamental misunderstanding of what makes the character sustainably compelling for decades.
If I'm wrong, and all these disparate, underdeveloped threads end up being weaved together into some kind of epic with a unifying theme, I'd gladly admit my rush to judgement and mistake. But there's no way that's happening. It's literally just a bunch of different shit that seemed like a good idea but was badly developed and never really went anywhere.
