They would have been better off if left to the mercy of a legion of ravenous sharks. No, seriously.
Melissa George as Jess.
It is at that precise point, around a half-hour into the film, that things get majorly weird and dire, and I cannot in good conscience discuss the plot any further without possibly giving away a truly interesting, intense, and (mostly) original exercise in terror that does a serious number on the audience's head. I can't even run most of the pictures that I found from the film for those same reasons, so I'll leave this as a painfully short review, despite how very much I would love to discuss my opinions on its every aspect. All I'll say is that TRIANGLE bears similarities to a handful of other films and television series that I could name — but won't — but it takes those possible influences and paints them very, very dark, with a central mystery that becomes more perplexing, horrible, and inevitably shattering with each passing minute.
I know this short review may seem like a cheat, but trust me when I assure you that you'll thank me for my restraint when you see it for yourself. TRIANGLE, a UK/Australian production, is absolutely not merely a popcorn-munching way to pass ninety-eight minutes, and it is also not in any way a feel-good flick, so approach it with the knowledge that something quite special and a departure from today's soulless, cookie-cutter, so-called horror cinema awaits you.
(Special thanks for alerting me to this movie goes to Russ Braun, an uber-talented cartoonist and dear friend with whom I have often discussed our shared filmic interests at length. He loaned me his DVD of TRIANGLE nearly a year ago and for a number of reasons I never got around to it until now, but as a result of his strong recommendation of this film, I will take his suggestions very seriously from now on.)
