The CGI of Babylon 5 looks dated compared to Voyager, which only came out a few years later. Its still serviceable, but also very noticeable
Spoiler: Babylon Squared
Im in the middle of watching Babylon Squared and in the scene where Garibaldi helps up Sinclair after he gets launched on B4, there is a dude in 90s era clothing just sitting on a pile of crates. Is that one of the film crew or what?
