Best serie of all time

I've never heard of that but for me it's probably GoT, Westworld, The Ozark in that order

Honorable mentions:

banshee
sense8
marco polo
breaking bad
better call saul
suits (except the last season since its shite)
ascension (small 6 part series worth watching)
the OA (watched the entire series back to back)
last resort
the walking dead(if you have enough time)
stranger things
the man in the high castle
house of cards minus the new season was really good also
