It makes me embarrassed to be an Australian. One of the worst scripts ever written. Even great actors like Richard Roxburgh weren't able to save this one. It started off well, with some great aerial photography, but soon went downhill with corny one-liners and awkward so called 'action' sequences. It amazes me how the characters could endure such trauma (being trapped in a cave with their friends and family dying), yet still manage to have poignant moments of reflection while trapped in crevices less than one metre wide. That actor from Fantastic Four (whatever his name is) will probably never work in the film industry again. His performance was more comedic than convincing. Help!!!!
