I will give a short ver review of this movie.
First off like many local HK film this one is full of local slangs and occasionally a few curse words. It's a Guy Ritchie Snatch kind of criminal comedy. It's full of over the top styling and some CGI that look rather low budget, even a little B movie like, for a 2015 movie. It's still an entertaining movie though.
A group of criminals dressed up as police, with a modded mini bus (very iconic in Hong Kong) as a police van. Their plan was to rob other criminals who smuggle money into Hong Kong in dead bodies (returning from China to Hong Kong for cremation). They ran into another group of robbers having the exact same plan.
The protagonists are likable characters. They started to act / think like they are the real police, and even managed to save a few victims. In the mix we also got a real life young cop who got the brains to piece together what these criminals are trying to do.
The story is based on 4 guys who got days jobs, making very little money, and always have ideas on scoring a heist. There is some brotherly love among them. The funny bits comes from their child like acts here and there, and some over the top actions.
The dialogs are not exactly witty and memorable. The acting is good given the quality of the script. The pacing is not bad. I didn't find any part to be too long, or boring.
There are some parts of the story that feels like is missing. Perhaps this is because of the Cocroach sub plot was cut from the theatrical release (rumored cut due to fear of China's censorship).
There is a post credit scene so you may not want to miss that.
