An astronaut has some sort of weird experience in space. He comes back acting funny. Does any one notice? Not until he really goes off the deep end. How will it all end?
Just because this is one-dimensional and predictable does not mean you can not still say “stay in the car.” And you don’t think having twins is spooky? Rosemary’s Baby never grew up to be a pilot. Yeah, and such common names like Spencer Armacost; what ever happened to Igor or Jeffery Dhalmer? They put in quiet space so you have time to think about what happened (or did not happen) and you call it dull. Do you really think that they would intentionally make a bad movie?
