Double Tap (2021)

Both stories are gritty, very realistic crime dramas. Both take place in a cold northern Chinese town in the midst of winter. The pace of both stories is slow, it's more about the characters than about the crime itself.
Especially the first few episodes of Double Tap reminded me of Black Coal, Thin Ice -- even though the stories differ greatly, the feeling was kind of similar.

Both dramas are placed in hard environment, similar mood, great cinematography. The actors are all veterans.

Same genre, 2 detectives works together solving an old murder crime dated back 30 years ago. The case involve kidnapping and murder.
