Galaxy of Terror(1981)

The first ten minutes of this really do have you reaching for the fast forward button, but once it settles down and we get past the characters/plot establishment sequences, it turns into an half-decent sci-fi murder mystery. The crew of a spaceship are sent on a rescue mission. When they arrive at the site, they discover that the other crew have been brutally slaughtered and, trapped by an electro-magnetic storm, they now have to look to their own self-preservation. B.D. Clark manages - actually quite an achievement - to generate a bit of suspense aided by Barry Scrader's slightly over-the-top score, but the acting is pretty dreadful. Erin Moran (whom I'm sure was in "Happy Days") and Edward Albert really draw attention to the low-budget sets and effects; and the story is all pretty routine
