I actually really like a lot of S1, they seemed to be going for something really interesting with good social commentary, but it fell apart I guess when they changed showrunners and I agree the end is pretty dumb.

S2 is good if you don't think about the logic of what they're doing too much, or ignore how it's completely devoid of any point.

S3 is good but again with a stupid ending.

S4 has a couple of decent episodes and I actually think they nailed the ending for the most part, I like how it's basically Star Trek: Arrival. But it's also maybe the most boring season of the show so far.
