Watched THE SHALLOWS, and PITCH BLACK ( Vin Diesel ).
THE SHALLOWS was much more exciting than I thought it was going to be. Lots of good Jumpy bits. But I thought it did start to become more and more less believable the more acrobatic and 'action hero' like both the shark and the girl became near the climax.
PITCH BLACK ( 2000 ) was Vin Diesels breakthrough role. A really surprising and good quality Australian B-Movie that introduces the character of RIDDICK. It's not AMAZING, but if you like action and sci-fi you could do a lot worse.
