I believe that science fiction is as profound as you want it to be or it can be very simple entertainment, and I'm all for very simple entertainment. Every now and then we all need to come home, veg-out, watch something and not think too deeply about it. It's what you want it to be. We tend to steer clear of being pedantic it's entertainment first, otherwise we'd be on a lecture circuit.
Learning what you don't want to do is pretty valuable, it may be as valuable as figuring out what it is you do want to do.
