People never seem to have nice things to say about Dayo Wong and Cheung Tat-Ming, but from my first exposure to the duo I can't see why. The movie is very funny, in a tragi-comic kind of way. Neither actor takes themselves too seriously, and most of the humour comes from them poking fun at themselves. Angela Tong is a welcome presence here too, as is the extended cameo from Matt Chow.
I really enjoyed the movie, laughed quite a lot - particularly in the closing scenes with Helena Law Lan. It's kind of dumb humour, but intelligently done, if that makes sense.
