Well it all imploded. No one really won.
Tom just became a puppet for a soulless monster.. but he did manage to change his power dynamic in a loveless marriage nevertheless.
Overall they were all bad people, we rooted for and liked some of them because they were charismatic as hell.
You can do a deep dive on each of them and their outcomes, it is all very interesting with the good writing and great performances.
Seeing Ken all sad puppy and losing his purpose in life, losing the family legacy.
Roman just trying to pose as a businessman magnate that is all fun and games.. all shattering and revealing just a messed up kid.
Shiv going back to a broken marriage and maybe in her mind saving the family from itself.
Connor still a goofball but maybe the best (in terms of a decent-ish guy) that the family has to offer surprisingly. Yet Willa was really looking forward to that distance.
Tom did succeed in climbing the corporate ladder all the way to the top. At great price, just a meat shield that after a few years will be discarded, has to put up with the prick boss trying to bed his wife.
Greg took his shoot but didn't work out so now he is in the swed's dog house, yet Tom did threw him a lifeline.
Things were looking up at the mom's kitchen but as the show taught us many times.. the world can go upsides down in moments.
All three siblings aren't good people and at the end of the day still billionaires with that high price sell. But for this people it isn't just about money, power is the real currency and they just lost it all.
