There is more than just a semblance. Planets have gravity! Flying into stars at the speed of light is unhealthy! There are a *lot* of planets in the galaxy! Being exposed to hard vacuum for less than 60 seconds requires emergency medical treatment!There has to be SOME semblance of adhering to a vague framework of physics as we know them or it just turns into a cartoon. Which it's getting a little close for comfort to in my view.
Either you haven't been paying attention or you really don't understand what the words "some semblance" actually means. That or you're just being unnecessarily hyperbolic and don't actually have a salient point at all.
