(Sorry for chaotic replies) Season 4 was a little weak, I thought, but everything else made up for it. That scene in S6 where Avasarala and Drummer meet gives me the shivers just thinking of it, it's so good!

OMG YES. I really wish they had produced more seasons. I haven't read the books yet (am in the middle of Caliban's War at the moment) but I feel there could have been a lot more show!
