I admit it wasn't my favorite of their live efforts. I think I agree with the energy problems (lacking sound during the Goshzilla clips, and then a riff-less plug for Sharknado 2 didn't help), but I also think the film itself was deeply sub-mediocre, designed to fill 90 minutes of digital celluloid as inexpensively as possible. It lacked the "flawed but interesting" flavor of Starship Troopers, the "laughable message" of Reefer Madness, or even the "visions of artistic grandeur that just don't manifest" of Plan 9 or Birdemic. The film was serviceable in its plot, storyline, effects, and acting -- neither good enough to be noteworthy or awfully terrible enough to be mockable. I'm not sure the riff-writers had much to hook onto; I'm trying to remember more than five riffs and I'm coming up short.
I'm happy to support them, and I'll probably be at Goshzilla (presuming GenCon doesn't interfere too much), but -- for me -- this wasn't the riotous good time I had at Starship Troopers.
