"Wai ngoh duk juen" (aka "An Eye for an Eye") is a very mediocre and archetypical crime action movie from the early 1990s of the Hong Kong cinema. But hey, if you enjoy that particular era and type of movies then writer Kiu-Ying Chan definitely delivers a movie that might be right up your alley.
I found "Wai ngoh duk juen" to be watchable, albeit a very, very bland movie experience. Director Sing-Pui O failed to make the 1990 "Wai ngoh duk juen" stand out in the vast tsunami of similar crime action movies that flooded the Hong Kong cinema back in the early 1990s. So that made watching "Wai ngoh duk juen" somewhat of a trivial thing, and the movie didn't really offer much of any real enjoyment.
The acting performances in the movie were a bit all over the place. Some of the actors and actresses actually put on good performances, while others were just over-acting to the point of it being cringeworthy to witness. The movie doesn't have any particular memorable stars on the cast list, nor any familiar faces really.
There isn't actually a whole lot of action throughout the course of "Wai ngoh duk juen", which also helps to keep the movie in the mediocrity lane.
My rating of "Wai ngoh duk juen" lands on a less than average four out of ten stars.
