This movie is really low-budget, but there's a lot of humour in it. I watched it a long time ago when I was a kid. There's nothing scary in it all and the special effects are hilarious, with the werewolves just looking like men in gorilla outfits.
There's also a very funny scene at the end where the neighbours see the two werewolves fighting in the bedroom and think that they're just people with some weird fetish.
Worth watching, simply for the laughs, but please don't take it seriously.
