Beautiful Cinematography, Beautiful Story, Must Watch!
7 October 2018 | by QuilescaSee all my reviews

This movie outdid itself - is simply not any dude bro action flick. It has everything that has been lacking in many blockbuster films that I have been waiting for - for years.

I can tell the team behind it were passionate about the project; the sound effects are poignant when it matters the most, the fighting scenes have humour with people flying out of view (I legit laughed out loud), and the cinematography (sometimes like wes anderson), with appreciated story boarding, makes for contrast and relief from the building tension in the full 117 minutes - which I was on the edge of my seat for the entirety of it.

The film feels like it was made with meticulous love and I recommend it for anyone searching for a ride or die action drama.

Hint: invest in the relationships as there is more than meets the eye.

Also, better than Infernal Affairs, better than the american version The Departed, which, come on, hollywood always forgoes about character and relationships to more fighting scenes.

The Merciless didn't skimp on any of the good stuff - it is in a league of it's own. Shippers will be satisfied - I can't wait to get my hands on a director's cut.
