It looks like it'd be a blast to buy if you had the money; your own private amusement park. Although I agree that a vacant rundown amusement park is pretty depressing and I can imagine that being there all by yourself would be spooky. It'd feel kind of that book "The Stand" where everyone is gone and you get a sense of dread. I mean, how many amusement parks have you been to where there's not one single other person. It would feel creepy to be there all by yourself because we are so used to thousands of people being around us. Think of it like being on the I-5 and not seeing one other person during rush hour, it'd be pretty scary wouldn't it. I think that's how this place would feel.
It's so weird how as much as we hate crowds, we need them in certain situations to feel secure. Even Disneyland doesn't quite feel the same with very thin crowds. I've been there on extremely light days and on elbow-to-elbow days and while neither is particularly enjoyable, you really do need some people in the park to make it seem fun. It adds to the "excitement" when there's more people around creating more activity.
