Made in 1966, this seems like a throwback to movies from the 50s. It's often paired with BILLY THE KID VS DRACULA as a couple of the most ridiculous monster movie ideas of all time. Which is saying something, considering many that actually got made. My disclaimer- I've never seen either of these movies, but they look entertaining.
Of course, a 90 second trailer can make any movie look like it will be good, that's what they are supposed to do. As long as the movie isn't boring I'll be reasonably happy. Of course, making Billy the Kid and Jesse James heroes is another thing, but I understand how that works now.
