This reboot could be excellent beyond all fears and jitters and I would still say you can't miss out the original Babylon 5, which is such a great fannish love of mine that I would say it's on a "how Fritz feels about works of Voltaire" level. :)

My offer of telling you which episodes can safely be missed, which are an absolute must, and which are "do watch, if you find the time" early on still stands, though. :)
