I’ll give one. Despite Sheridan and Delenn giving that speech about rejecting the Shadows and Vorlons and making their own way, the Vorlons won. The Army of Light, the Rangers, and the Interstellar Alliance are all in line with Vorlon philosophy, they run on Vorlon tech, most members were Vorlon allies, and they still oppose former Shadow allies and destroy Shadow tech when they find it.

Another is that the Shadows should have had their own Kosh, a character who was still comitted to the original goal and hadn’t succumbed to motive decay. Shadows believe in strength through adversity, so one setting up obstacles with the expectation that the cast would overcome them and grow stronger cpuld have been interesting.
