Great movie. Saw it in the late 80s (came out in 88 on VHS here). Wasn't even a teenager yet. It was amazing and the opening music stuck with me for a lifetime.
Watching it as an adult i can see why it would annoy people seeing it for the first time - it's basically a goofy kids adventure movie more than it is a horror movie. But it's still great fun.

Also To think that Kiefer was only 18 at the time, and he looked cooler than i ever have in my entire life. It's not fair.
