George Romero introduces the tales similar to Creepshow. I was expecting something light with a twist, but that was not the case. In the first tale, 3 spelunkers go into a cave only to get trapped...and one is injured. We know what happens here. The unexpected part, the part that should make the story a hit or miss, comes after the rescue. In this story, it was pretty much a miss unless you watch strictly for blood and gore.
In the second episode a college history professor (married, 2 children) is sleeping with one of his students, Alison. He is a stickler for being on time to his class and not missing it. As it turns out Alison is "late" and is pregnant with his child. She comes to class with a gun, points it to her head, and she doesn't "miss." The interesting part is the expected haunting. As expected it starts out slow and takes some twists. Perhaps the best of the three.
The third episode is more akin to the Creepshow variety. A security guard steals Mars dust from NASA to cure his terminal wife of cancer. She becomes a human sexual dynamo (nudity). Unfortunately the effects wear off and the guard must get more.
The plots weren't overly exciting. Romero uses his special gore/make-up effects as a substitute for a good story. If you keep your expectations low, you won't be disappointed.
