And what's extra cool is that every single character had a back story. Not "came from a troubled home" or "drinks on the sly" but like you could sit there and discuss what they were doing in grade school and what kind of mom and dad each of them had. It was like that. It was written that well. And every character was ACTED well. None of this, "Oh, I'm just a bit role, I have to a) be small b) be loud and try to steal the show." Nope, each actor gave it 100% of what it needed to be perfect.
I can't believe this was written so long ago, especially when I think about what was contemporary at the time. Harold Pinter is god and I worship at his altar.
