The pacing of these old Science Fiction movies can be brutal and this one is no exception. It's sloooooow. However, its got some neat old sets, a unique alien craft, and a cheap but freaky looking alien menace. Honestly, I can't even remember much of the movie other than the different looking black and white visuals. I do recall that there were some early representations of zombies too, but not of the eat-your-flesh variety. I wouldn't recommend this unless you are a die-hard '50s B-Movie freak. Even then, you may have to fight off the urge to nap.
