A very brief mention that a man slept once with an already married woman.

A woman is seen with a nightgown. No cleavage is shown however she is not wearing bra.

Characters refer to a trap known as the 'Meat Grinder', and people being killed in it - although it is never explicitly stated how it works.

Several misuses of "G-d" and "L-rd" (misuses or not is not clear)

Very infrequent mild language, especially considering the length. A few uses of hell, damn and shit.

Characters drink alcohol in a few scenes.

One of the characters claims that he is a heavy smoker; however, he is only seen smoking in a few scenes.

Also, the idea of an alien place where people disappear may be unsettling to younger viewers.
