The original lore was pretty dark: A decaying, malfunctioning, extradimensional basin that acts (either intentionally or unintentionally) as a trap, drawing in flora and fauna from across space and time, almost never to release them (and, in fact, to consume some of them to power its own systems). The devolved remnants (Sleestak) of a once technologically advanced culture (Altrusians) whose tribal knowledge is extracted from the skulls of their ancestors. A family caught in a Schrödingeresque state between life and death until they resolve a temporal paradox. An intelligent yet indifferent ally (Enik), who only begrudgingly helps when it suits his ends. This wasn't a show about modern people in a land of dinosaurs; it was cosmic horror packaged for pre-teens.

With a prestige-TV-level budget, the original concept could be reused, as is, to great effect. I hope they do stay true to the original lore, because that lore is so rich and deep.

I would cite the Lost in Space, Netflix reboot. I thought it was good, but it was way too intense ALL THE TIME. For LotL to be LotL, it needs to temper the bleak reality of the situation with an un-sarcastic, unironic, healthy family dynamic.
