the wrong end of the telescope

My brother's 21st birthday is tomorrow. He just had knee surgery, in another three months he will have MORE knee surgery (fuck fuck fuck, I feel so bad for him) and I need a present that will help him sit still this summer when he needs to rest.

So. He and his girlfriend just finished watching all of West Wing and they LOVED it. I need long series that are just as good and engrossing, which I realize is complicated, but yes. Help? He's seen Game of Thrones, and it's also not quite long enough yet (more than 2 seasons is preferable but not absolutely necessary).

Also, I'm still taking Avengers or X-men cuddling prompts in my last post.
