What has happened to all the great murder mysteries?

I was trying to find a good movie to watch with my boyfriend and then I thought to myself "I feel like watching a good twisted murder mystery" the problem came to me when I couldn't find out with an outstanding review. I tried my film noir and still nothing new caught my eye. I've seen all the old and I want something new, but really? These days who is going to make an amazing murder mystery that keeps you guessing to the end? Have we lost all our lost puzzling writers to advertisement and trashy TV? or is there just no room in modern popular culture for a screen viewing that actually makes you think? Nothing could beat the best now, they stay cemented in your mind. For example I don't think I will ever lose that one scene in China Town (1974, starring  Jack Nicholson  and Faye Dunaway) between Gittes and Evelyn..

Evelyn Mulwray: She's my daughter. 
[Gittes slaps Evelyn] 
Jake Gittes: I said I want the truth! 
Evelyn Mulwray: She's my sister... 
[slap] 
Evelyn Mulwray: She's my daughter... 
[slap] 
Evelyn Mulwray: My sister, my daughter. 
[More slaps] 
Jake Gittes: I said I want the truth! 
Evelyn Mulwray: She's my sister AND my daughter! 


Both actor and actress, completely perfect for the scene and completely perfect for there given roles in this tale, upon tale, upon tale. 


What about our TV shows of the same genre? Can't find one these days that isn't full of drama and love affairs. I JUST WANT A MURDER MYSTERY TO WATCH WITH MY BOYFRIEND! 
Oh Agatha Cristie, the world does miss your presence.
