I see your point. It seems every company is in a rush to catch some "cinematic universe" lightning in a bottle, but at least DH is giving us an Aliens series (Defiance) that seems to be its own thing, as well. I just hope they have some more freedom this time around. FaS seemed almost like a waste given how restricted they were.
That being said, I'm liking the interconnected stuff so far, so I'm interested to see what these series have to offer, especially since they're being helmed by really good writer.
I asked Randy Stradley on Twitter if this is a sequel to FaS, but he hasn't gotten back to me.
