A mediocre comedy from Herman Yau. The early '00s weren't Yau's best period and it shows. Happy Family is a basic comedy that just hobbles along without ever making a worthwhile impression. It lacks Yau's typical edge and comes off as commercial filler in between more challenging projects.
The lead actors do a decent job, but the rest of the cast is well below par. Loudness and overacting are often confused for comedy, the soundtrack feels like a complete afterthought and the cinematography is plain and uninteresting. If you ever wondered what Hong Kong filler looks like, look no further.
The plot itself is slightly amusing though. It's not great, but at least it kept my attention until the end of the film. It's definitely not enough to actively recommend Happy Family, but I've sat through worse films. At least it's short and mildly amusing, at the same time it's also wildly plain and forgettable.
