I've only seen three episodes of 'Daredevil' so far, but I knew straight off that I would have loved to add it to Earth Prime-Time, the main Toobworld. Its energetic fight scenes, strong characterizations, and writing that never feels cliched would have made it the leader of all new shows set in Toobworld.
So it figures I have to give it up.
The background of Matt Murdock's world is definitely linked to the theatrical movies of Marvel (most of which have been absorbed into the Toobworld Dynamic - but into Comic Book Toobworld.) This is especially true with the first "Avengers" in which the climactic battle destroyed the West Side of New York City. So 'Daredevil' is in the same world as 'Agents Of SHIELD' and 'Agent Carter'. Unlikely as it may seem, Matt Murdock could show up in an episode of 'Agents Of SHIELD' one day. (But it would be more likely for him to team up with the 'Arrow', despite the competing corporations involved.)
But there's another reason why 'Daredevil' couldn't be in the main Toobworld - he's already there.
In 1989, Matt Murdock aka Daredevil, became a fixture of Earth Prime-Time thanks to an appearance in a TV movie that continued the legend of Bruce Banner, "The Trial Of The Incredible Hulk."
Here are two tribute videos to the character as played by Rex Smith:
Sure, that Daredevil doesn't measure up to the new incarnation, but unless there are strong extenuating circumstances, Toobworld must remain loyal to previous versions of shows - not just 'Daredevil', but the 1966 adaptation of 'Batman' and the 1979 'Battlestar Galactica' over their later remakes. (Especially since all three had ties, both actual and theoretical, to other TV shows. In Daredevil's case, it was O'Bviously to 'The Incredible Hulk'.)
Them's the breaks....
