The science elements also don't operate on real world known or speculative science. The space ships behave like they move within an atmosphere and make audible sounds in the vacuum of space, for example.
Well, lots of what can be considered sci-fi do similar. I can't recall a movie that really highlights the fact that there's no sound in space. A silent movie would kinda suck. Lol.
And certainly no flames in space.
Ever wonder what a nuclear explosion would look like in space?
