A singularly unconvincing parable, ultimately hamstrung by awkward, choppy storytelling. Mark Harmon plays a divorced radio psychiatrist in Seattle who reluctantly takes his son and daughter on a holiday to a lakeside community in British Columbia where, according to Indian legends, a sea monster is lurking; by the time you discover whether it is or not it’s pretty hard to care as much as the characters, who undergo all sorts of improbable changes by listening to their inner selves. Directed by Rick Stevenson, from a script he wrote with Icel Dobell Massey and Ninian Dunnett; with Joshua Jackson, Harley Jane Kozak, and Sarah Wayne. (JR)
