Season 3 perfectly wraps up the series.

Though I have 3 concerns
First the stadium, once a sanctuary, becomes a chaotic battleground, which is gripping but sometimes feels inconsistent.
Second, Eun Hyeok's transformation from the cocoon is a standout moment, though it raises questions for neohuman stuffs that aren't fully answered.
Last is the girl with the power to turn humans into monsters feels underutilized and somewhat irrelevant to the overall plot, leaving a sense that her potential was wasted.

Well despite these issues, this season beautifully melds the action and character depth from Season 2 with the intense, iconic feel of Season 1. It’s a satisfying and emotional conclusion to a series that kept me hooked from start to finish.

Yup, this last season is better than the last season of Game of Thrones lol

PS
S1 > S3 > S2

and I will rewatch it all again.
