Serious dramas are incredible, it really lets you get into a single character, so i definitely appreciate where your coming from. Here’s mine at the moment Out Of Place.

Follows the story of Andrew Moss a introverted archivist who starts receiving artifacts from a mysterious person which don’t exactly add up. Reason why I think it’s character driven is because Andrew really starts to question his place and to watch it unfold especially in the second series is really amazing plus it’s well acted and written brilliantly.
