I think the episodes are too long. The average episode is, what, about 75 minutes? In contrast, the Rod Serling Twilight Zone episodes were 25 minutes (seasons 1–3, 5) and 51 minutes (season 4).
The premises are often cool, but it would be better if they edited the episodes down, like what was done with Star Wars. https://www.youtube.com/watch?v=GFMyMxMYDNk
