I got the first season of Babylon 5 to see what it was all about....Now I'm a BSG fan and come from the TNG/DS9 days as well and I felt Babylon 5 was too cheesy and too weak! I could see how it would have its own following but it's nowhere near the levels of BSG/Firefly etc.
Everyone to their own

, but it is a bit unsual for a ST:TNG and DS9 fan (especially if you are of that era like me) not to like Babylon 5. In many ways DS9 was a rip off of B5. At its time it was a multi award winning TV program.
All I can suggest is that you watch season 2 and 3 of B5 as that is where the story really kicks off. Season 1 basically sets the scene for what is to come. Season 1 can be more appreciated after you have watched the entire thing. Babylon 5 has a much more epic story line than any of the Star Treks, or BSG. I would say B5 has a fan base not all that far away from Star Trek and miles larger than BSG, Firefly and the like. Although if you like Sci-Fi you tend to like all these series (as I do) but you do tend to have favourites, in my case its B5, Farscape and ST:TNG.
As all things in life though, people like and dislike different things.
Not original music, but just an idea of some of the battles
The Whitestars were just awesome

Everything in Babylon 5 was huge, the capitol ships really are huge at miles long. The Earth tech is particulary interesting with spinning gravitational sections as seen in the Omega class destroyers. God im being very geeky now
I should point out that the CGI on recent B5: The Lost Tales was done by the artists that did BSG. Shame the DVD wasn't any good. I think the opening scene in the video above is from that. Foundation imaging that did the CGI in the first few season of B5 also did the CGI for later seasons of ST : Voyager.
