this film did not attempt to supply any meaningful info about what may or may not have happened at Montauk and was truly the worst film I have ever seen! it was simply an excuse for a demented (if talented) guy to portray his weird mindset and the 3 main 'knowledgeable sources' were to my mind certifiably insane and did not offer one shred of useful information, nor indeed one shred of evidence.
it started well enough, but then went nowhere logical at all - I only put myself through the agony of watching to the end see if Garentano offered any facts to suggest or deny any wrongdoing, but he offered no conclusions whatsoever.
the only science fiction here was in the minds of those sad folk who featured in the film!
