That's (partly) what I meant when I wrote 'rational & scientific'. Rules-y and consistent are included in that.
Ah, okay. Well, it sure doesn't mean that to me. The magical "Law of Sympathy" is by no means rational or scientific. But if the author tells me that the rule applies to magic in the world, I expect the author to stick to that.
Let me try to explain where I'm coming from. I don't ask that my science fiction to be consistent and rules-oriented, let alone my fantasy.
Well, that's your own problem
For example, I'm fine with the 'rules' governing Star Trek transporters being: they generally work fine unless it's dramatically appropriate for them not to, in which case they may simply cease to function, necessitating a little shuttlecraft drama, or malfunction in a metaphoric and/or plot-enabling way, perhaps by splitting you into your co-dependent id and ego, or by creating a doppleganger of a past self.
Thing is, there's nothing all that inconsistent about the usual transporter shtick. Transporters work, in general. But they are mechanisms. Mechanisms break, or fail in conditions they weren't designed to deal with. If your car can break down, or not make it up a really muddy hill, why can't a transporter have issues?
And no, the "but if they were that unsafe, they wouldn't use them" argument doesn't hold much water with me. Being in Starfleet at all is incredibly risky. Ships get blown up, eaten, infested with alien fungus, and just slip away into the timestream with great regularity. An occasional transporter malfunction in the highest-risk ships in the known galaxy is not really an issue, to me
In the most recent movie, however, is an instance of them breaking their own rules, and having it irk me considerably. We are given to know that transporter have a limited range, so we need starships. But then a villain, through no known effort, has a transporter that blows that range out of the water, in such a way that should reshape the fictional universe. He can transport between star systems. This feat is more important than any other event in the movie, as it means we no longer even need starships, and it is just glossed over. The death of the very concept of Starfleet is at hand, but meh, who cares?
