It's wild to me when fans of the show disregard the first season. To me, that season is pretty much perfect. Three arcs - a detective story, a motley crew, a political thriller - pay off feels so great when it all comes together at the end. Season 2 was such a drastic change in pacing, concept and 'feel' that I didn't want to keep watching. I felt a little betrayed that Miller wasn't actually the main character.
Besides Amos, I don't really care about the Roci crew. I had to wait until Ashford came along in Season 3 for a new favorite character.
All in all - Avasarala, Bobby and Drummer carried the series for me.
Yeah, I never watched Atlantis. My ol' friend who recommended SG-1 (years ago) said the other series weren't worth watching, but maybe he just meant Universe. What was wrong with Universe?
I just watched some YouTube clips of Atlantis and saw Colm Meaney makes some appearances. So.. adding to the list!
