i saw this film when i be a student back in 1988 or 1989. a friend and i hire it on video . it have get to be one of the most dire film i have ever see . totally derivative and unoriginal and cheap and tacky and badly act and buttock clenchingly bad . the special effect for the space battle be lift directly from battle beyond the star . strangely enough and i have see another film that have do this and so maybe the maker of bbts sell the right to that footage to make some money . bearing in mind that i be write this review 11 year after see the film and i would give it a huge thumb down at negative .
