In theory, 'Killer by the Lake' has all the ingredients for a classic detective thriller: a complex plot, three-diemnsional police characters with intereting personal lives, decent acting, and a gorgeous Alpine backdrop. But somehow, as with its predecessor series 'Vanished by the Lake', it just feels a little too formulaic. Our screens are full of detective dramas, and it takes something special for one to stand out: in this case, all the elements are lined up, but there's no unique ingredient that brings it to life. You'll see many less professionally-made series, but there's a certain lack of inspiration here.
