I would say this grew on me as the story developed.

I enjoyed the last episodes the most, when things were falling into place, and the script included some refreshing scenes like the diarreah-scene (!).

The main cast was ok. He was a bit too “flat” sometimes, but I guess it was really challenging to not be, due to his character.
She had some scenes were she was very convincing, and mostly her scenes were ok.
Second male lead I found to be a bit over-the-top childish sometimes.

Music I did actually notice for once; well suited.
