I just finished a month long rewatch of Babylon 5, and again, was reminded of why I think it's the second best sci-fi universe out there (behind Star Trek, of course).
That said, I really don't understand why people compare Babylon 5 to Battlestar Galactica (RDM version), considering that B5 outclasses that mess in every way imaginable. Hell, it's even better than the 1978 version, a show I love quite a bit.
I agree with the others here. Stick with it. You'll love it.
