and to me feels just a tad more mellow, elegant and Californian thanThe Colbys' theme
Somehow I usually associate California with "aspiration", and the Falcon Crest theme captures that combination of prosperity & doom (with its middle section informing "be aware!").
The Colbys, its characters and premise, have no real beginning - it's all very established and their goal and challenge is to maintain that status quo.
Apart from the obvious sci-fi element I also find The Colbys theme kinda WASP and Ivy League, the kind of Other Family the parent show needed in their Dynasty universe, but couldn't handle without the risk of diminishing the Number One family.
Cecil and Jeff were Carrington sidekicks, good sidekicks, but nothing more than that. Dynasty invented the Fallmonts only to demolish them a.s.a.p. so obviously there was something about it that didn't work.
Personally I think there's something delightfully perverse about the blatant Dynasty Extra Time. It's the same, but it's not. A distorted mirror version with very similar yet very different characters, and a pompous, exhibitionist theme that challenges and taunts The Believers who think that this show really shouldn't exist at all.
