"City Under Siege" is a lame title for a movie like this. It's description suits the plot but not the atmosphere... it makes it sound like some 80s Hollywood blockbuster. Anyhow, its a weird and quirky Chinese sci-fi action in the vein of XMen. A troupe of circus performers are exposed to a chemical which was hidden in old gold mines by the Japanese during WWII and it lends them superhuman powers. With an arrogance of invincibility they embark on a rampage of mayhem. It's actually really stupid. The movie is too comical for it's own good and the dialogue (translated subtitles) is terrible. On the positive it's a stylish and great looking movie. There's some interesting imagery and action sequences but its overall very underwhelming. Bugger.
