I hated the ending But I'll explain why: After all of Sung Jin-Woo's effort, the decision to reset the timeline was deeply frustrating 1st: All the character development throughout the series was basically erased, Jin-Woo sacrificed himself countless times, faced powerful enemies, and lost friends in the process, All that growth and the relationships he built were simply forgotten, The emotional connection we had with the characters was destroyed, as everything they went through was annulled 2nd: The ending suggests that Jin-Woo returns to Earth as an ordinary person, without powers, This completely contradicts the idea that he should be rewarded for his sacrifices and relentless effort, He deserved a more gratifying ending, where he could live with his loved ones and be recognized as the hero he is 3rd: Another disappointing point was the lack of closure for the other characters, All those who grew, changed, and developed throughout the story were left without a proper ending In summary, the ending of "Solo Leveling" threw away the character development and narrative built throughout the series The timeline reset was a narrative choice that left the story senseless, undoing all the emotional impact and Jin-Woo's achievements It was an ending that did not do justice to what the series built and to what the fans expected
