Starting with the traditional Star Wars opening shot, this movie begins with a spaceship swooping into view. Only this is no ordinary spaceship. This one's guitar shaped.
The ships crew are supposed to be on a scientific mission but they have heard some music that they liked and are now searching for the source.
After failing to find what they were searching for, it's time to investigate a little planet called...Earth.
Now don't let the word 'rock' in the title fool you because if you're expecting this to be another Rock 'n' Roll High School or Detroit Rock City then you'll probably be dissapointed.
This is 80's nonsense at it's finest and if you're a fan of bad movies then you'll get a kick out of this.
There are some great funny moments, like the shrunken and cryogenically frozen crew which are represented by some action figures in a fridge...no, I'm not joking, they're on the shelf just above the chocolate milk.
And of course there are the brilliant unintentionally funny moments, such as Craig Sheffer's song towards the end...the one I like to call 'ballad of cougar man.'
Still, no matter how ridiculous this movie gets it is weirdly enjoyable and I did spend most of my time watching this with a half smile. Either that or it induced a stroke. I'm not sure.
If you like bad movies, 80's nonsense and want to watch a musical with appearances from Jermaine Jackson, Michael Berryman and a lake monster then this is worth a look.
