Babylon 5 is epic... but also filled with a lot of details. It is not what I call easy viewing. Long story arcs that, if you're not really interested, seem to drag on. But the biggest disappointment for me was the primitive CGI. Star Trek got a face lift... sure wish they'd do the same for Babylon 5.
Anyway, Farscape is much easier to digest. Very entertaining stories and superb acting. If only they got 2-3 more seasons out of it. So much potential.
