Really fell downhill after season 3 and the switch to Amazon. Went from an incredible high concept sci-fi story to just run of the mill Hollywood action drivel.
of course everyone is entitled to their opinion but I don't see any reasonable view of that being the truth. Season 4 is a little like that but 5 is firmly the best of all the rest of the seasons and it has a ton of Hard SciFi in it.
Same feeling, in a way I regret to have continued after season 3, I were warned that season 4 was not on the same level as the previous seasons but to continue to watch.
Season 3 ended so beautifully.
