This is my gosh darn CHILDHOOD! I remember dressing up as Kolchak for halloween one year, and of course no one knew who I was, but man...I felt awesome.
I rarely describe something as "feeling perfect," but this show feels perfect. Sure, there are a couple episodes that are a bit of a slog, my personal least favorite being "Primal Scream," but I'll be damned if I don't remember "They Have Been, They Are, They Will Be..." Gave me nightmares for weeks as a child.
My favorite would probably have to be "The Werewolf." It's the one I remember most fondly, and probably has the best setup to a monster in the show.
Is the show perfect? No. Does it feel perfect, and will I give it 5/5 because of that fact? Yes. Such a damn good show.
