I read one of the books when I was 9 or 10 and I will never pick up another one again. What was apparently the "Most Mild" of the goosebumps got me so scarred that I couldn't sleep for months, not only did the "happy endning" turn into a trap where characters had to run and fight for their lives in order to escape a playground of deaths that monsters place humans in for entertainment. Those who were fans of the books said that the books were no where near as scary as the show. Now, I still remember direct quotes from that book, and I was TERRIFIED, It gives me shudders to think about it, and I did not nor do believe in monsters when I read that. Common sense has it ranked appropriate because there is no blood or gore, but there is WAY intense scenes that NEVER END. SPOILER ALERT for one of the books/episodes! After MANY very intense near death experiences at a park, the workers are revealed to be horrible monsters who tell them "it's all a joke, you're on a hidden camera show for a monster channel" they say, here is the "real" exit over this way, then they lock them in a dark hall, tell them "NO ONE EVER SURVIVES HORRORLAND" then set various traps and monster on them, one character says "They REALLY ARE GOING TO KILL US!" then they escape with the monsters chasing them after the fight for survival ends.
