If you're looking for "hard" SF, you're not likely to find a pure example outside of novels. A few movies have come pretty close; TV shows have not. The convenience factor of things like FTL drive is just too tempting.
I hadn't quite thought of it in those terms. I suppose I make a distinction between 'supernatural' and 'pseudoscience'.
I suppose it's hypocritical of me to say I'm willing to take a little bit of pseudoscience while rejecting the supernatural but it does end up being the case (in a way it's an argument for another day).
I should make a point to say that I'm not against watching shows and movies that contain supernatural elements (and in fact many of my favorite shows do). It's that I'm specifically looking for shows that break that norm.
