I thought that I couldn't hate S4 more but then I remembered that...
Five and Diego die without reconciliation and hating each other
Klaus dies without knowing how the Original Ben died
Diego dies without knowing if Lila fell in love with Five or not because she never answered the question
Lila died after not seeing her kids for nearly 7 years
Luther died without finding Sloane, the only person he was in love with
Allison died leaving behind Claire, the one person she sacrificed everything for
Ben died as a monster without his consciousness, unable to say goodbye to his siblings
But most of all, they all died to become flowers meanwhile the fucking Handler had a happy ending🤡
