“Sea Fever” (** out of four) was a not-bad sci/fi melodrama about an Irish boat crew (Dougray Scott, Connie Nielsen, Hermione Corfield, and others) who become stranded at sea and soon find themselves under siege by a parasite in their water supply which gradually kills off their crew one-by-one. Reasonably well executed and filmed but horror buffs will note that this is perhaps an all-too-obvious clone of “Alien”, “Event Horizon”, “Virus”, and many others. Has its moments but never fully takes off and becomes satisfying.
