To save you some time and effort … this review is for dyed-in-the-wool film buffs. No one else, you see, will ever understand or appreciate a film such as “Destination Mars.” And more’s the pity, since this 2002 spoof is one fun film. However, you do need to be intimately acquainted with the films of Ed Wood Jr. and of the naive science-fiction flicks of the ’50s to get the point of the whole thing.
