I tried watching it for the first time a couple years ago, and . . . eh, something about the acting felt off for a lot of the characters, especially the human ones, and specially especially Commander Sinclair. So dry, it was like eating unbuttered toast. Without anything to drink.
I got a soft spot for Garibaldi for his love of Golden Age Cartoons, and I really liked Londo, his speech patterns and general hammyness were quite a treat, but it was not enough to keep me going. I think I quit around when Psychic Chekov showed up.
