The Hannibal series maintained my interest throughout, largely carried by Mads Mikkelsen
Look for the original Swedish/Danish version of ‘The Bridge.’ It’s been remade with USA/Mexico and UK/France, but the first is still the best. I usually hate shows with subtitles, but this one kept me going for every season. Body turns up on an international bridge, half on one side and half on the other. Two very different police detectives have to work together to solve the crime.
‘Culprits’ is from the POV of the crooks. After commiting the perfect crime, a now reformed crook is pulled back in when the wealthy victim comes looking for revenge.
Criminal Minds
It’s old but Tinker Taylor Soldier Spy is great.
Fortitude Session 1 is great. Season 1 is also self contained and the mystery is solved. Season 2 was a new mystery and kind of meh.
ALIAS. “She’s a grad student! She’s a spy! She’s a grad student! She’s a spy!”
