The Detective 2 (Hong Kong, 2011)

Private investigator Tam still longs for the day he can join the Bangkok police force and work alongside his old pal, Inspector Chak. When Chak is reassigned under a pig-headed new chief inspector, Tam is hired to help investigate several mysterious deaths, believed to be the work of a mentally unstable orphan. As his investigation brings him deeper and deeper into the child’s psyche, memories of Tam’s own childhood as an orphan resurfaces.

The standalone sequel to 2007's The Detective, is just as thrilling. The plot may not be as good, but it's still worth checking out if you're a fan of intense murder mysteries.

Genre: Crime/Thriller

The Detective (Hong Kong, 2007)

A private detective is drawn into a complex murder mystery when he is hired to track down a missing young woman.

A plot easy to be drawn into, and it holds up all the way, never getting stale. The lead actor is perfect for the role, and it's great fun seeing him try to solve a murder case that's getting more and more dangerous by the minute.

P.S: Don't let the extremely weird and terrible opening song scare you away, when it ends, it never comes back...

Genre: Drama/Thriller
