To me the best seasons of sci-fi are usually the last season..
except b5 their best season was 3 out of 5
For most television shows, the second and maybe third season are usually the best. That’s where they reach their rhythm and know the characters but before they fall into familiar patterns and retreads. As hard as I am on the new BSG, I’ll give it praise for one thing. It’s managed to constantly change from season to season so that it never falls into a rut of being the same old thing over and over again and that’s a trap that all too many science fiction shows fall into.
