The Big 4 are the adopted children of Petrus, who has trained them to be perfect assassins well atleast 3 of them as the youngest one mostly is a bait. Petrus is murdered leading to the big 4 to go on hiding while his actual daughter becomes a police officer and is obsessed to solve his murder. How the daughter teams up with the 4 to take revenge on their father's killer, forms rest of the story.

The tone never gets serious with constant funny lines thrown around. Many jokes don't land correctly, but the loud comedy somehow carries the story forward while the bloody action set pieces take care of the rest. Much of the jokes fall under the silly category but the action set pieces gets more fun whenever they get silly which should be credited for the innovativeness. The story is built up for a sequel so the main reason for the conflict is still kept unrevealed.

Timo Tjahjanto is one of the best action directors in the business. If you need convincing, just watch Headshot (2016) and The Night Comes For Us (2018), both of which deliver amazing fight choreography and brutal violence aplenty.

Unfortunately, Timo doesn't appear to be so great at comedy, of which there is lots in The Big 4; his attempts at humour in this film are pretty terrible, making it quite tedious at times, especially whenever the film takes a break from the kicking and punching and shooting and explosions.

Things kick off in fine form, as the titular quartet of vigilantes make a gang of evil organ traffickers pay the price for their crimes. It's gleefully OTT, the screen painted red with the blood of the guilty. The foursome -- Topan (Abimana Aryasatya), Jenggo (Arie Kriting), Alpha (Lutesha) and Pelor (Kristo Immanuel) -- have been trained as assassins by their adoptive father Petrus, whose real daughter, policewoman Dina (Putri Marino), has no idea about her dad's other 'children'.

Three years later, Petrus is murdered, and Dina investigates, discovering her father's secret...

The comedy kicks in when Dina encounters her 'brothers and sister', who have now retired from the killing business, and the film suffers for it, the silliness being more irritating than funny. Of course, the film ends with a jaw-dropping action set-piece in which Tjahjanto piles on the stylish ultra-violence with aplomb, but it's not easy to forget all of the daft nonsense that precedes it.

9/10 for the action, 2/10 for the rest, which averages out at 5.5/10 (rounded up to 6 for IMDb).
