I get claustrophobic in tunnel scenes. Why do Sci-Fi film-makers have to do that, other than to save money on their grossly opulent budgets?

And was it the planet's indigenous in habitants that did in the first space alien in the initial flashback, or was he committing suicide because he was being marooned on a planet without WIFI?

So many BIG questions that were not resolved in this film to my satisfaction.
