Do you have any particular disappointments with B5?

Well, it's tempting to point to the premature resolution of the Shadow War, but I'm going to go with the lack of resolution to the mating experiment with Lyta and G'kar.

I'm probably in a minority here, but I never liked the actress for Ambassador Delenn and the love story between her and Sheridan seems so forced, I roll my eyes whenever it's brought up.

The Shadows were 'foreshadowed' for so long, and then they end up being something so tangible, so mundane, so solid, so rigid..

When they could've been something more 'ninjalike', mysterious, never-seen-properly, a bit like the 'alien' in the first 'Alien' movie, maybe. The concept of 'shadows' has SO much potential, and the 'shadows' being some ancient species was hyped and foreshadowed so much, and everyone was so scared of them..

..then they turn out to be just badly modelled, rigid things that don't have very 'shadowy' powers after all.

I mean, sure, some.. but SO MUCH MORE could've been done with them, and the whole thing just became a wrestling match between one, boring, mundane, predictable species and another (that was also supposed to be like 'antithesis' of the shadows, full of wisdom and 'angelic' qualities - but also they turned out to just be too 'human' and egotistical in the end. It's like, what's the point?)

My disappointment about all this is, things, entities and beings became diluted and three-dimensional, when they were hinted to be something so much greater and multi-dimensional, independent of time and space - something 'beyond', something 'astral-etheric-divine' quickly became just 'plastic toy soldiers blasting each other' in the mundane world.

It's like people can imagine 'wonder', but they can never put it on screen in a believable way without diluting or 'mundanizing' it until it's just another boring cliché concept.

Why couldn't the shadow ships be 'ethereal', not really in any specific location, or multi-locational, instead of solid 3D objects?

Why couldn't they be more an 'esoteric force' that influences people and beings, and even bends light, but doesn't really have any solid substance to attack? They could dim the lights of an area (or seemingly so, creating a dramatic effect although the light isn't really affected) while influencing someone with EXTREME temptation and lust and promise to fulfill and satisfy that lust...

The Byron arc was lame and almost ruined season 5. I'd have preferred a time jump at the start of season 5 and they concentrate on Londo's reign as Emperor instead, the whole Drakh war and seeing what happens with John and Delenn's son and the keeper he was "gifted" on his 16th birthday. Also Bester's fate and Lyta too. Instead we got Byron. Sigh.

Too much use of apostrophe in character names. This is lazy writing. Low production values. B5 was not a network series: it was a syndicated series, sold to local stations who had very weak—or no—network affiliation, the Stargate and Total Recall 70 series. Too much tedium in the narrative. It was great, if you’re 12. This would not fly today.

How did a low-functioning alcoholic like Garibaldi even get his job, let alone keep it?

Biggest disappointment: not nearly enough of Tracy Scoggins. She was the only reason why I watched this.
