Ok gonna ask this question say what if they did a movie with Sarah being a bit older do you think she would fall in love in jareth or at least admit to having feelings for him?

Depending on how you look at it it could be different answers. One theory is that jareth is a figment of Sarah's imagination and represents what she wants in a man they definitely could not be together because he's just a part of her that she needs to outgrow. Another theory is that maybe this was all real and jareth actually was in love with Sarah (not the healthy kind of love though more like an obsessive type) plus they're both immature and probably weren't the right match for each other. Or a third would be he was trying to brainwash her into giving him Toby. Although this might not be very likely since Toby didn't change at all during the movie and looked like he was more interpreted in getting the crystal than being saved. Plus it says in the book "the king of the goblins fell in love with the girl and gave her certain powers". Also she asked for Toby to be taken and jareth offered her a chance to run the labyrinth. He was just flirting with her along the way and didn't do anything to kill Sarah completely or throw her friend hoggle into the bog even though he threatened him many times throughout the movie. But yeah it probably would be very hard to mark because the labyrinth could be interpreted many different ways. My view is jareth was in love with Sarah but she didn't feel the same way mostly because of the age gap. Hardly any 15 year olds are mature mostly they're still just starting to date and navigate their way into the wonderful world of love. There are even some older teens who have never even had a boyfriend or their first kiss or don't want to date at all. So basically I'm guessing Sarah's a newbie to dating and relationships but anyway jareth is much older and represents to me a handsome middle aged man. He's probably had more experience and the relationship wouldn't work out even if she was older. Even if he was immortal she would still age and die before him (unless she was turned immortal). So yeah this is my thought out opinion. Hope I helped a bit. ;)
