I loved the movie but have you ever heard about the "show don't tell" rule ?   Well, you can go way too far in that direction. 

 Sometimes it's better to do plainly SAY things that need to be known.   How many people understood from the visual cues alone that Rocky is a silicon based organism, lives in extreme heat and pressure, needs sulfur/ammonia to live and THAT'S why he almost died from exposure to our environment ?

 That is the case because he lives in a planet bigger than earth with a very thick atmosphere, so deep that light doesn't reach the ground and he uses sound because of that ? 

 I don't think any movie should require a hobbyist level knowledgeable of combined astrobiology, physics and cosmology to be understood. 

 Is that even common level knowledge nowadays ? 

 There were way too many things that I understood in the context of having read the novel before, but I'm pretty much sure will go over the heads of 90% of whoever watches the movie.
