I love the idea of doing something with B5. I have it on DVD and recently bought it again through Amazon Prime because I re-watch it quite a lot.
Londo Mollari is my favorite character (I have his action figure - unsigned :sad face:), but if I had to choose a race to play it would be the Minbari. The Centauri men are so much fun to watch, but the women have such a cloistered and limited existence it doesn't seem that fun. At least in the Minbar temple, I'd have had an entire year to laugh!
Concerns about the reboot include the following: we already know who John Sheridan is; he doesn't exist on B5 without Delenn and we already know who she is, and what their story is; it can't be done without the conflict between the Centauri and the Narn (substituting other races in the same conflict is a bad copy) and they introduce the Shadows as a part of their relationship, and we already know who they are (realistically, Mollari and G'Kar represent the best juxtaposition between the two races we could have hoped for); the story can't be told without the recent conflict with the Minbari, without it why build a station at all and which race would contribute to the cost and oversight?; only a few of the non-aligned worlds are actually known to the viewers, but this we, well, we know, and; the end of the story has already been told, how do we deviate from that? Do we toss everything we know about B5 that made it great? Is Ivanova going to be heterosexual (heaven forbid)? Will Garibaldi not be an alcoholic (who would he be?)? Will Franklin not be an addict (another loss to his personal journey)? Will there be no transformation for Delenn (is Sheridan really going to be attracted to a full-on Minbari?)? What about the attachés Na'toth, Vir and Lennier; they were instrumental in the storytelling (and moving it along) and so well played? I'm assuming that the Shadows and the Vorlons will be a staple in the story otherwise, why "reboot" the story at all? What about the telepaths? What about getting surviving cast members to make special guest appearances? Peter Jurassic should be a must to play a Centauri!
Back to the analysis:
So, I have some concerns and these are only the immediate ones. I suppose more could be done with the aliens on the Non-aligned board, telepaths, Vorlons and Shadows. There is definitely room for more storytelling, but we are all so familiar with the main characters and cultures that too much deviation might cause a ruckus with fans. I don't envy your struggle with keeping Canon and reinventing characters. I'm looking forward to see what you do. Best of luck!
A quick aside: Na'Toth rocks! At least Caitlin Brown's version does. She is canny, brilliant, snarky and a physical powerhouse. Her replacement was more of a place-holder and never lived up to Ms. Brown's portrayal of the character. She's my second favorite character.
I suppose that going back to the Dilgar war would be worth exploring, but that's not B5. It would have to have a completely different cast of characters, and that might be a good thing (spin-off!). This could be where we meet the Vorlons for the first time and get Easter eggs about the Shadows. The B5 universe is worth exploring. We might find a different and new race with special powers who manipulate time, space or matter and are in conflict with a sister race that evolved along a different path and they have a different special power, possibly controlling plant life and the elements. Humans get caught in their conflict while trying to get them to help in the Dilgar war, and then try to bring them back together. Blood (alien) has been spilled and trust is gone. The relationships can only be repaired one adventure at a time, through one community at a time. And then, just when things are coming together, they evolve. Just a thought.
Another thought, part of the B5 story arc could involve a Centauri lady who is high-born, fallen on hard times, and has the ability to have visions and interpret them. She doesn't, of course, but she can. She could interweave throughout the story lines helping, hindering or just being too bored, or selfish to manipulate. I like her already. The crew gets taken in by her, doesn't trust her, but then relies on her in times of duress.
More to come on story lines...in the meantime, share yours.
