nice gaijin has offered an excellent idea about that watching of programs, but I would like to offer a modification to the idea.
Older jidaigeki is an excellent way to slowly absorb listening comprehension without a person fully realizing what is happening, IF they are into the drama itself.
I wrote "older" up there, because the ones that came out from about --- well, after San Biki-ga Kiru --- I don't remember the last year of that --- it only ran a couple of years --- but the newer ones/jidaigeki are horrid. (My view, of course.)
So to be more specific about 30 plus years ago I used the jidaigeki to help me with listening comprehension just by enjoying the drama itself, because you hardly need to actually understand what you are hearing as you watch the situations unfold and after a bit you find yourself actually starting to understand this-and-that and step-by-step you start gaining better listening comprehension.
There is also the tossing in of some variations to modernish Japanese and that can be really useful down the road.
Okay, so jidaigeki is explained here:
And to get you started on YouTube:
長七郎江戸日記 第1シリーズ 第1話「風流双面草紙」(1983年)

Anyway, jidaigeki may not be your cup of tea, green or not, but just an idea. And mainly if the watching of a show for them young folks is more not your cup of tea.
