The Beast of Yucca Flats

The Beast of Yucca Flats (or Atomic Monster: The Beast of Yucca Flats) is a 1961 American horror film directed by Coleman Francis.

Plot
While attempting to defect to the United States, a Soviet scientist is caught in an atomic bomb test and is mutated into a horrible monster.

Why It Sucks

 * 1) The movie's opening scene, which features a nude woman getting strangled, has nothing to do with the plot, and was only added because Coleman Francis liked nude scenes.
 * 2) The camera used to film the movie couldn't record audio, so all of the sound was dubbed in post-production.
 * 3) * As such, in practically every scene, the actors are facing away, off-screen, or far enough that matching lip flaps wasn't necesssary.
 * 4) * The narration sounds extremely awkward and stilted.
 * 5) There are numerous scenes that go on and on and serve no purpose beyond padding the runtime.
 * 6) There are numerous plot holes.
 * 7) Terrible acting. Tor Johnson as the Beast's strangling looks extremely unrealistic. And his victims just seem to die immediately upon being shaken for a few seconds.
 * 8) Overall low production values.
 * 9) Unconvincing special effects. When people get shot, there's no blood.

The Only Redeeming Quality

 * 1) The film is so bad and surreal that it's still entertaining to watch.
