Premiere: Tuesday, Jan. 9 at 9pm Eastern, simultaneously on Disney+ and Hulu.
The latest trailer shows scenes from Daredevil (the Netflix series), and Hawkeye (with some implied spoilers).
The series is rated TV-MA, which is the most "adult" rating of a Marvel series to date, but matches the Netflix Daredevil rating.
This is also the first series to premiere under the "Spotlight" brand.
Echo will be the first series under the Marvel Spotlight banner... Just like comics fans didn’t need to read Avengers or Fantastic Four to enjoy a Ghost Rider Spotlight comic, our audience doesn’t need to have seen other Marvel series to understand what’s happening in Maya’s story.
My suspicion is actually that the dumping of all episodes at once is due to it being TV-MA, because Disney doesnt want to promote such a violent shows for multiple weeks on Disney+. Just a guess.
