Howlingly funny. Guy Ritchie in the Filipino idiom (though the ending is more Tarantino than Ritchie). At the same time, Guy Ritchie is a rather limited filmmaker, and Big Time's flaws are similar to your typical Ritchie film.
Still, it is impossible to dislike a film whose best joke's punchline is "Toni Rose Gayda". I doubt if it will survive past today in SM, so let's hope they have the good sense to release it on DVD or VCD.
