Prepare to work for it. Series were longer back then, and all of season 1 is slow. Later season 2 starts to reward this effort. There are a couple of episodes in S3 & S4 that aren't great. Otherwise - S3 and S4 are absolute top notch. They blow the shit out of any TV made before or after, on every level and in every way. Be prepared for B5 to set a standard everything else fails to meet by a very, very, very long way. Try to avoid spoilers.
The deconstruction of falling stars.. the jailbreak plot device was implausible to me when I was younger, somewhat plausible when I was introduced to VMs, and now with LLMs we're probably already there.
S1 isn’t great, it’s more adventure of the week to get used to the characters, life on the ship etc. is not bad but it’s pretty dated. But it sets the backdrop for 3 seasons that changed TV reaching out even today - planned multi season story arcs.
