Welcome to Arrow Beach

Hilarious title song by Lou Rawls (can someone be a sport and let me know the name of it?) and some tasty nude scenes can't overcome a real muddled film. Sure it's explained that Harvey has a "taste for cannibalism" but where is the rationale behind it? We see a brief flashback scene of Harvey leaving a vintage-Korean war airplane along with a messed up looking crew of overacting teenagers (and Harvey doesn't look any younger than he is in the "present" day scenes -- check out the sideburns) but what exactly happened there? Perhaps the Dutch version has more footage? Also, what about the Stuart Whitman subplot? He was all hot to find out the truth but that sort of faded away. A real mess ... can't believe Harvey checked out with this as the last bit of work on his resume...
