I'm not a fan of these kind of films.
That said, I was surprised to see this ran for a little over an hour, so I figured, well, why not?

The plot is actually pretty original for this kind of low budget, sy-fi channel type fare and, where the budget's clearly low, the sets all serve their purpose and fail to pull the viewer out of the mood by having glaring errors. The CGI though...
This one starts well and, adapting very quickly to the truly awful CGI, there's little to really ruin the film, because we already know it's never going to be amazing or try to be anything other than a group of people surviving a tsunami... and now have to also survive a killer shark!

Hot girls? Definitely. Capable male lead hindered by past trauma? Yes, all the clichés are here - right down to the English-speaking blonde girl who sounds like English really isn't her 1st - Hell, 2nd, even - language, but given the genre, we already knew what to expect.

So, the only questions remaining are: was this as bad as the usual and was it worth the running time?
Well, as pointed out above, I don't normally like this kind of thing, so I'd say it's above average and, as for the running time... well, it's something like 65 minutes of so-so entertainment where the brain effectively gets switched off for chill out time.
Nobody ever starts watching this type of film expecting to find a new favourite to tell friends about, but for what it is, it's entertaining.

Somebody seriously needed to check the anatomy of the CGI though, because the fin should be in the middle - and is for the most part - but for sheer drama, it apparently moved all the way up to the shark's mouth in a few shots!
But who cares? After all, this was never going to win a Chinese Oscar.
