Friday the 13th Part VI: Jason Lives is a great example of "Not to take it too seriously", because when your movie opens up with a guy getting his heart punched out of his chest by Jason and then a spoof of the Gun barrel from James Bond with Jason added in, you know this movie isn't trying to be serious.
The story is about Tommy Jarvis, who's intent to killing Jason once and for all, goes to the graveyard to destroy his body. But instead of laying the killer to final rest, he unintentionally reanimates the monster and a new killing spree begins.
Jason Lives is one of those "It's so bad that it's kinda hilarious". The movie dose have it's moments of laughter and awfulness.
