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).
