A lot of people will tell you the first season isn't worth watching. I'll admit that the acting is a little cheesier, and there are some episodes that you might think are a little heavy handed... but they set the stage for you to feel what you feel when the things they were exploring in the b plots come back in the main arc of the show. There will absolutely be moments 3 and 4 seasons in where you go 'oh shit, they set this up in the second episode!' Because it was heavy handed enough that you will remember it, even thoughbyou didn't get it at the time.

To an extent, you do have to get over the cheesy acting. I see it more like a play than a show with overly realistic acting. Some of the acting is a tool to get things across. And you know what? I don't know how well Londo and G'kar would play out without that cheesy background. There hasn't ever been better character development than those 2.
