All of the hype surrounding 'Triangle' has nothing to do with the actual quality of the film or its storyline, but instead the coming together of three of Hong Kong's biggest and most respected action directors Ringo Lam, Johnny To and Hark Tsui, famously responsible for films like 'City On Fire', 'Election' and 'Once Upon A Time In China' respectively.
That kind of hype can often be an indicator that the movie itself isn't up to much, and in this case that was true. The idea was that each director would get 30 minutes of the 90-minute movie each, but the story itself was so disjointed anyway, that really had no effect at all, good or bad.
No aspect of the story moved with any real pace and the acting was, for the most part, the kind of ham-fisted overacting Hong Kong cinema is, sometimes unfairly, mocked for in the West. This is particular true of the segments where the main protagonists, a trio of friends who are trying to retrieve a buried treasure, are on the run from the various people after them; slapstick gags left, right and centre.
Given the reputation attached to the three big-name directors working on this movie, it was a disappointingly boring effort with very few saving graces. The basic story was weak, the acting poor and the pace inadequate. A shame, in a sense, because the three segments idea could have been a good one.
