Now don't get me wrong, I love this film not because it's a well-crafted classic but simply because it's a fun and terrifically 1980s effort, complete with big hair, flashy cars, crazy sweaters and a ditzy heroine. It's undeniably cheesy and I completely agree that a decent budget and more talented leads would render it a sci-fi classic, however this is a bit like an extended episode of Quantum Leap, and as such is cornily brilliant.
Nancy Allen, Hollywood's go to girl in the 80s for cute dreamy heroines, does a good job here, however Michael Pare is like a more wooden Marlon Brando as out-of-time sailor David. Classic horror writer John Carpenter adds some much-needed pizzaz to the title credits in his role as executive producer, but there is little for sci-fi fans to get excited about, with some average SFX and little attention paid to the time-travel aspect of the story, other than some bewilderment on the sailors' part as they attempt to come to terms with postwar society.
See this if you fancy a lighthearted, whimsical and undemanding movie; after nearly thirty years it still stands up as a solid if unspectacular fantasy film.
