This movie reeks of loose actor direction and a randomly executed plot(!) The basic idea of catacomb horror sounds promising, so it is quite frustrating to watch this tedious flick. Shannyn Sossamon has more or less been granted the same screaming-and-horrified part as Franka Potente played in the just as pointless/wasted London subway horror "Creep". The rest of the actors seem to improvise their parts quite a lot, so we never get to know whether Pink COULD have any hidden acting talents. Even though I probably love the completely unique Pink more than any other living music performer today, I have to admit that in this film she is definitely NOT playing anybody's sister! Instead, she is a somewhat spooky and unpredictable party girl that (ab)uses her charisma to stir things up along with a whole bunch of VERY unreliable young men, all played by Romanian actors. If you want good underground tension, I suggest the highly underrated "The Cave" (2005) (http://www.imdb.com/title/tt0402901/). If you want some good chasing & suspense horror, I recommend either "Haute Tension" (2003) (http://www.imdb.com/title/tt0338095/) starring Cécile de France or the 1978 hospital classic "Coma" (http://www.imdb.com/title/tt0077355/) starring Genevieve Bujold and Michael Douglas. Good stuff.
