An entertaining action/crime thriller...

With this being a Hong Kong movie was already more than enough to grab my attention. So when I sat down to watch "Line Walker" (aka "Shi tu xing zhe") then it was without knowing what the movie was about. However, I did know that it had Louis Koo and Francis Ng on the cast list, two of the more renowned Hong Kong actors.

Usually I am not overly keen on action/crime thrillers, but I do still watch them, and I must admit that usually the Hong Kong cinema usually do spew out quite good action/crime thrillers. So this genre was definitely not a cumbersome anchor to the movie.

The storyline, was initially quite simple; a group of undercover police officers have their true identities revealed because of a leak. However, there is more to it than just that. And director Jazz Boon and writer Cat Kwan did manage to keep the movie quite interesting and also ensured that the audience are thrown curve balls every now and then as the story arc takes a surprise turn and twist.

There is a good amount of action combined with some drama, but also a good amount of suspense. So there is something for just about everyone to enjoy here.

Louis Koo did a good job in carrying the movie alongside with Nick Cheung. Now, I am not overly familiar with Nick Cheung, but he was quite good in "Line Walker". I am a big fan of Franic Ng, and he was quite good in this movie as well, just a shame that he didn't have a bigger role. I can't really claim to be familiar with Charmaine Sheh, but she also did a good job.

All in all, if you enjoy a good action crime movie, then "Line Walker" is well-worth sitting down to checking out, regardless of you liking the Hong Kong cinema or not.
