Great production-values and colourful images creating a dreamlike quality to parts of this mystery-thriller are among Triangle’s best assets. The director is Christopher Smith, a Brit known for horror films such as Creep (2004) and Severance (2006). This time his aim is to be more subtle and clever, toying with loops in time and logic. The wanted effect is arguably to chill and fascinate, but apart from an eerie atmosphere, which holds up until about half-way into the picture, the effect Triangle gives is rather annoyance and frustration. I have rarely seen a film as eager as this one when it comes to encouraging the viewer to analysis. The problem is that the abundance of plot holes, logical fallacies and twist will wear you out before Smith has even started the denouement of the psychology which he proclaims lies behind it all. This is no Memento, and certainly no The Machinist.
