I would have watched Twilight Zone and MST3k during Sci-Fi's prime, but I didn't have the channel up 'til around 3 or 4 years ago.
(My exgirlfriend really likes the present-day SyFy, which I thought was weird since it is universally shat upon.)
I used to watch MST3k on Comedy Central, back in the day, *puts on hipster glasses* when the channel used to be good.
All I watch now is *puts on another pair of hipster glasses* Netflix, PBS, History Channel, Travel Channel, National Geographic, etc.
