What I have come to realize being a JJ Abrams/Bad Robot fan for over 20 years is that most of the early TV series (Alias, LOST, Fringe, Revolution, and the very short-lived Alcatraz) had a Star Wars foundation, but with different genre skins (Espionage, Epic Adventure, Crime Drama, Dystopian, etc) on top.
What I mean by this is, most of these stories are like Star Wars because at their core, they are multi generational family Sagas set within metaphysical universes. And with main characters coming to terms with the truth of whom their parents (or parental figures) really are, often by facing them in some way.
For LOST this notion was personified through many characters, because it was more of an epic than the other works, but really when it gets down to it, it's a very intimate father and son story about Jack Sheppard not understanding or being able to forgive his father.
IMO the Island was a time-machine that housed all conceivable manner of life extension through it's exotic light-water or it's "heart" (Life, Death, and Rebirth). The Island was pushing the characters SPIRITUALLY forward, by making them confront their past, and ironically with what they didn't know about the connections they had to each other and/or each other's families, as they began to try and make their own. For Jack in particular, this also became about a need to save the Island.
Also many of Bad Robots early works, and especially LOST, often referenced or had allusions to Star Wars, as many who worked on the series are known Star Wars fans, including JJ Abrams who has now gone on to co-write and direct Star Wars: The Force Awakens & Star Wars: The Rise of Skywalker, suggesting that his company's early works prove why Disney heads, such as Kathleen Kennedy would think he is the right fit for any 'Skywalker Saga' film.
In addition Damon Lindeloff, one of LOST's head writers and executive producers, went on to write and executive produce an adaptation of The Leftovers, which also like LOST, was about facing great losses, death, and/or The Unknown via the disappearance of people's family members.
