It almost feels like the writer was going for a two-hour pace and then just slapped on a mindless climax.
Disappointing in that there is a nice hook to set up the story, a villian whose appearance and quirks reminds one of "Blowfeldt" from the James Bond movies (complete with Oddjob-esque henchman), and an element reminiscent of POW camp movies like "The Great Escape" or "Stalag 17". The entire episode is comprised of a series of vignettes that do not combine to make a cohesive narrative. Ultimately this crazy-quilt of a plot leads to a very unsatisfying end. There were a couple more rewrites and tighting to do to the script before they set this one to roll in front of the cameras.
