I watched the first two episodes last night, mainly because I liked Raymond Lee in Kevin Can f*** Himself. It's definitely going to have a couple extra overarching plotlines, one that no doubt involves the search for Sam Beckett, and another with a present-day conspiracy. The reverence for the original show just bleeds through. Lots of split-second plot twists, lots of Ziggy, lots of hologram work.
It's woke, too. Very multicultural, equal representation, that sort of thing. I'm a fan of it, if they can build character depth and not just shallow caricatures, it'll go a long way to bring society to a point where people are just people.
What else? The cheese factor is high, lol. It's not for fans of realism. They have Ben doing multiple spacewalks in Episode 2, ffs. But why not? it's sci-fi fun. If you liked the original, you'll like this sequel series.
