I'm watching this show again, after having the DVD set for about 8 years and watching them once before. There are only 20 episodes, which is a shame, since it's quite a good show. I watched most of the episodes when it was first run and they were really scary then.
The show holds up really well, especially the writing. I'm taken by how much the X-Files followed some of the stories- a firestarter, aliends (duh) even the devil all show up in both shows. Here's the opening which is both whimsical and slightly macabre all at once.
