Holy Freakin' Cow
They had money enough for special effects, and to hire actual brand-name movie actors, but for some reason they decided to get people who actively hated & feared, and aggressively misunderstood, science (even ordinary grade-school science, like How Ocean Waves Work) to write their science fiction movie.
(Fortunately we just got the dvd from the library & didn't spend any money.)
OTOH, if you like classic space opera style sci fi books, you could read the Commodore Ardcasl Space Adventures by Lee Payne. (Disclaimer: a relative of mine. Also, unfortunately, only available on Amazon.)
My favorite part is the Space Goats in book #4, although the lizard-horses in book #1 are also quite fine.
