Both pieces focus on slow quiet and dull lives where one finds meaning in another. My liberation notes is a show and hence at a slower pace than the movie Vertigo. Very similar in that the main characters don't talk too much, relatively quiet, and find comfort in each other. Both female leads are sad and hate their dull lives.
Both revolve on an gay couple finding their way in the world, however in Dear Ex, this couple spins off a story, rather than them being the story. A very great watch.
