Wow. Have you missed the MST3K folk as much as I have? The good news it that they seem to be more on top of their game than ever. Want more good news? This is only one of 3 -- THREE, folks!!! -- new movies of skewered movies they've released. Huzzah. The world is a better place.
Why yes, that IS the TARDIS making a surprise, split-second, silhouetted appearance. So clever of you to notice!!
