Sphere (1998)

Something alien is found one hundred and sixty fathoms below the ocean’s surface, so a group of specialists are called in to examine it.
An uninspired opening gave way to what seemed to be a structured Hollywood attempt at creating a thinking man’s sci-fi, but the bad drama music that bludgeoned its way into proceedings kept me suspicious. It turned out to be an indication that the cerebral was just a lure, or perhaps too challenging to maintain, and that a descent into tedious semi-horror was just around the corner.
