The thing about Farscape is not that it happened to share a lot of familiar science fiction (and specifically) space opera premises, character types, and plots..
The thing is it mashed them together and spun them around and twisted them on their head. Farscape revels in the genre and it
screws with the genre. It'll take a familiar sci-fi plot and then ram it into an unrelated plot to see what'll happen, or take it an unusual direction, or just dick about with it.
Just because other shows had used the same material before doesn't mean Farscape wasn't doing fresh and really interesting stuff with it.
However, I do like the suggestion of remaking Crusade because there's some interesting stories to be told there and I'm not so connected to the actors for their particular characters with the exception of Galen.
A remake without Galen is something I'm on board for (hell, without Technomages altogether, because besides Michael Ansara's Elric they were all completely insufferable).
This is like asking the Battlestar Galactica fans do you want a remake a few years before Ron Moore got a hold of it... so ask me in a few years.
I was here when that happened. Trust me, there was a lot of anger. There were people who wanted to see Richard Hatch's pitch of a renewed Battlestar Galactica, or the Bryan Singer/DeSanto one - and people who hated the changes (President Roslin is just a stand-in for Bonnie Hammer and proof of how terrible the Sci-Fi Channel is one argument I remember reading).
The more I think about it, the less appealing a remake or a continuation is. Why not a BRAND NEW series? New ideas. New characters. Why go over the same ground? Why not a NEW thing to be a fan of?
Eh. If you mean 'a BRAND NEW' space opera series, then your distinction isn't as meaningful as one might think. On the other hand, a space opera series still has some familar conventions, without which it is simply no longer in that genre (you can't make a space opera series that's set in the 20th century, never leaves Earth, and has no futuristic technology of any kind).
On the other hand, a remake may be a thorough reworking of a series premise, retaining the genre and ideas and names but flipping them about as to be unrecognizable. Ron Moore's Battlestar Galactica was a good example of this.
Honestly? I'd like another good space opera show on TV that I like watching. A new show like RHW's
Defenders would be good, but I'll really take whatever.
