I don't love the episode, but I don't hate it. It scared the crap out of my seven year old self when it first aired. I couldn't watch it until many years later. So for that, it kind of does have a special place in my memory.
I'm in the same boat, I was 6 when I first saw it and was bloody terrified
If you can overlook the blatantly obvious science issues its a good way to kill 45 minutes.
