prometheus bound misunderstanding

it was difficult trying to differentiate the topic of pain and pleasure in real life and in the play. perhaps I'm not understanding the full purpose of the chorus in this play but I would like to know how it is different in the play to real life because i feel like its just simply similar to watching a scary movie. Does the fact a God and a Titan being involved in it have an affect on this difference, or is it that they're being told first hand? i know i was suppose to be answering this but im unsure as to what answers i can provide for that with explanation that makes sense. i would just be repeating myself.
