Se7en (1995)

Yeah, this movie is pretty old, American Horror Crime film, but if you like detective films, this is a MUST. And it's pretty violent, and luckily, they don't even show some violent places. It's like saw, only bit less violent and has lot more mystery in it.
And a little about plot, and please, don't read it unless your not watching it:

Spoiler:

There were happening more and more murders, soon realizing, that the murderer is a serial killer and all murders are related to Seven Deadly Sins. When the first five deadly sins and murders are done, the killer comes to police and gives up. He says that the 2 detectives Mill and Somerset must come alone with Doe (serial killer) and he will reveal the last 2 dead bodies.

I love Se7en! Brad and Gwyneth were still very young . Great cast and very exciting and thrilling movie

I saw its name the first time at internet, when searching a great mystery film. When i found it, i was like: "Nah, i don't think it's a good movie"
And after few days, maybe a week it was shown on TV, and since it's gonna be shown on TV, then why not?

Yeah, and then i realized, that it's the perfect mystery crime film

Haha and aren't you just glad you spent the time to watch it as it turned out to be a great movie that you couldn't afford to miss? It happened to me before too but I couldn't remember which movie. But there are also some movies you are sure will be great but turned out to be a bad one.
