"Sunstorm" is one of those junk flicks like "Maui Heat" which have some lame action/drama as an excuse to get a bunch of T&A in front of the viewer for pure titillation. However, in this bottom-of-the-barrel film, Marvin, Eisenman, and crew have substituted Keach and Derek for titillators in an apparent attempt to bring credibility to what is just another lousy flick. In spite of a beautiful Puerto Rican backdrop and a bunch of babes, "Sunstorm" is a messy slapped together B flick loser with no reason for existing save a pay check for cast and crew. Pass on this turkey. (D)
