It just me, I dont like long serie (except thoses will self contained episode) Even something I liked, the 3 body problem, had 2 full episode (close to the end) of filler in 1 season. And they already got past the 1st book in that season, so they have room to 1 or 2 more season at best.

5 season?.. no way I can invest in that, but cool for those who can enjoy this kind of show
