The Shallows is a slight, but surprisingly effective, thriller right until its inability to find a satisfying conclusion. The setup is straightforward: a young woman becomes trapped by a shark whilst surfing off a remote beach in Mexico. Blake Lively is an unlikely choice for such an individually focused survival film but she offers a strong performance with believable peril and pain, whilst grappling with the emotional issues that drew her out to honour her mother’s memory. It is a shame, then, that the film’s final minutes leave the audience incredulous rather than impressed.
