As much as I enjoyed PX for its quality, pacing and style, it was never my favorite. Somehow the drama amidst a far-stretched subject (read: unexplained creature) seemed out of place. What the Bleep was that thing anyway? At times it seemed to take itself too serious. Maybe if instead of an incomprehensible being it had been a more human nemesis (terrorists, madman/men, etc) it would have felt more real to me. That it was shot as a full-length feature explains a lot of course, where pacing is concerned. Still, the acting was decent to good and the director certainly knows how to work his magic. As low-budget goes, this is a keeper. Just my worth of salt.
But, gorramit, what was that creature?!
