TV just isn't the place for pure, rigourous science fiction.
I think it could be, if it was backdrop. If it was the main selling point, it would fail.
Also, I don't know how long that would stay interesting. A speculative fiction TV series that locks itself down into any assumptions/dogma stands a chance of getting predictable.
Science fiction is about breaking boundaries, not adhering to them.
So I think "pure" science fiction could be a launch platform, if you will. But if you never leave it...
