There's a lot of great shows in the series. Of course for Suspense there's a lot to choose from, with over 900 episodes floating around. I'm more fond of the early Suspense because they tended more towards fantasy and supernatural. Later in it's run it got more grounded in standard murder/mystery type stuff.
And Escape is always a lot of fun, with classics such as Night of the Hunter and Three Skeleton Key (which was also on Suspense).
I've used this blog as a guide for several shows that I otherwise had no idea about (like The Sin Eater
) which was very interesting because I run the Manly Wade Wellman website
and it reminded me a lot of one of his stories.
