I watched the film and . . . er . . . it's still on the fence!
I expected better quite honestly from all the posters and trailers. It's quite underwhelming. The night shots are quite realistic (compared to CGI) and brings to the edge of the seat but the end is . . . bad. Bad CGI, bad lines, wrong dialogues, one minute its realistic, the next it's just wacky. The movie looks as if directed by a 10 year old!
Disappointing really, cause the story is some-what on par with "Black Water' franchise, expect with sharks! 47 meters was miles better than this one.
Points must be given for realistic survival experience, a bit realistic shark behavior (hunting as a pack). It is not totally bad but, its not superb either.
