If you suspend belief for 80 minutes, this is an OK film, nothing more; nothing less. Reviewers who have commented that this French production is a breath of fresh air compared to "flashy" Hollywood thrillers must have watched a different film - this is every bit as "flashy" as a Hollywood production.
Although fast-paced and well acted, the plot stretches credibility on more than a few occasions and this spoils what could otherwise have been a very good action thriller. Had it been 30 minutes longer, I feel that the director could have made a more believable and ultimately more enjoyable film. As it is, everything is just too rushed and, plot wise, extremely convenient.
The director's earlier film, 'Anything for Her', is far superior to this effort and was remade by Hollywood. I doubt very much that there will be a Hollywood remake of this - the director's already done the job for them.
