I mostly rewatch old episodes of childhood favorites like (in order of # of rewatches):
-Are You Afraid of The Dark
-Tales From the Crypt
-Tales From the Darkside
-Goosebumps
-Pete and Pete
-The Tick
-The Critic
-Dr. Katz Professional therapist
The last four on that list are actually good shows. The first four on that list just have nostalgia going for them.
