B5 is my favorite of all time series. The cgi at the time was amazing and attention to physics added an extra dimension. Trek's model ships we're beautifully detailed, but watching B5's graceful motions only served to ridicule TNG with its three-point turns in space, or DS9's use of tractor beams in battles to deflect disruptors. At this point, Trek battles made the Power Rangers seem plausible.
Despite the perfectly adequate special effects, for an upgrade to nuBSG standards and a HD release, I'd sell a kidney to fund a blue ray player!
