“Maneater” (* out of four) was a toothless horror potboiler about a group of friends (Nicky Whelan, Porscha Coleman, Kelly Lynn Reiter, and others) who are besieged by a ravenous shark and it’s up to a seasoned professional (Trace Adkins) to come out to sea and save them. One more unnecessary addition in the seemingly endless glut of killer-shark movies with little style, scares, humor, or much of anything else. Country music star Adkins does what he can here but unfortunately this just isn’t going to elevate his acting career to the “big time”.
