I haven't even bothered that, because apparently the only full episode I actually saw was like one of the worse ones, I saw it as it aired and just never got to watching it. I know people really like it but I just got to it. Hope you like it with the rest.
Oh no! Yeah, it's hit or miss, I've turned off shows because I saw a random episode that was the worst introduction ever, but I've also managed to get through some pretty slow shows to find some gems a few seasons in. I know next to nothing about Babylon 5 but hopefully it's more on the gem side!
