If you're expecting a history of the park, talk of attractions, or even narration of any kind, you'll be disappointed. The talentless director basically just set up his camera at random spots and filmed whatever was happening at the moment. I'm not really disappointed in how incredibly dull it is, so much as how little effort was put into the making of it. In modern times, I could just wander around with a GoPro on my head and get similar--or better--footage, upload it to Youtube and have put as much effort into the project.
On the other hand, if you're feeling nostalgic about late-80s/early-90s NYC, and just want background noise, this would do the trick.
