Will This Be Better Than Galactica 1980

Or will it roughly be the same thing albeit with slightly improved visual effects?
Lol - I am surprised you have heard about that obscure and disastrous TV show. I remember it coming back on satellite TV (possibly the early Scifi Channel) briefly when I was a kid for like a week or two but otherwise that's all it did after its initial run.
I'm sure any attempt at an ALIEN show will be just as uninteresting as any of the other modern attempts to turn well-remembered genre films into shows. The WILLOW, LORD OF THE RINGS, DARK CRYSTAL, and DUNE shows have all been underwhelming, boring, and terrible, despite high production budgets.
