British character actors struggle to create suspense, with limited props in a science-fiction horror set on a remote, over-heating island. A film which could be worse, though which could be a lot, lot better, with a miscast here, an impenetrable character there, not meshing as well as they do in similar genre pictures. Even the plot, which should be key, is lost under a few bumbling sub-plots. Some dated relationship politics and a love triangle which fails to ignite. Some enjoyment, but mainly at instead of as a result of the film.
