This film is brilliant - I don't care what others think - It is your basic adventure time travel film. I think the plot is genius - When something disappears nobody thinks what's going on while it's invisible - This is what happens in the film as a ship is cloaked during world war 2 to prevent radar detection but the ship completely vanishes - while invisible 2 crew members jump overboard into one of the best time warps i've ever seen, into 1984 - I think the acting, effects and overall tension of the movie was way ahead of it's time and will remain my personal favourite film.
