Don't understand the hate... Nor do I fully understand all of the science, however I understand enough to know the creators have done their homework and that what is transpiring on screen is entirely plausible so far.
The casting is excellent, the acting is top notch and while it seems the space scenes are largely behind us by episode 4 they were at the time cinematic quality with great SFX on a par with Gravity, and the suspense is palpable.
Yes, the pacing is somewhat leisurely, but I personally wouldn't have it any other way, this is not Marvel fayre.
I've read other reviews that compared this to The Cloverfield Paradox, and if that's what they were expecting, I understand why they are disappointed, but IMO the two are only comparable at an elevator pitch level, despite sharing a severed arm and an experiment in space that's where the similarities end.
Beyond that, I can only imagine that like Caldera's particle, this show is being observed in different states simultaneously by different viewers.
