Lliam is great
3 February 2012 | by (Dallas) – See all my reviews

Multiple people have compared this to Neeson's 2008 release of "Taken." Both have a similar concept; Liam goes on a fast-paced journey to retrieve something special that has been taken from him. This time it is not his daughter; it is his mind. Unlike "Taken," "Unknown" is more of a suspense mystery than an action flick. There are some chases and fight scenes, but that is not the main focus. The movie's plot is focus and it is unique for it is unpredictable. We are confused like Neeson's character and there are times we don't know if he will succeed. There are multiple twists and unlike most mystery thrillers, it took me more than half through the film to figure it all out.

In short, "Unknown" is a fairly decent mystery thriller. Good performances. Good story for a mystery. Good music. Good cinematography—I particularly like the whole gray, dreary atmosphere that reflects the film's location's bleak weather. Good twists. Good suspense— the sound mixers must've had a kick in adding emphasis on sound effects to startle the audience. The one thing I will note is that Liam Neeson is really showing his age. This is not necessarily a bad thing; on the contrary, it helps his character out. It gets tiresome that Hollywood always uses the generic 30-something year old actor with smashing abs who is tossed into a terrible situation. It is nice to see an aging actor play an upper middle-aged man who has perhaps lost his mind while running away from people trying to kill him.
