I'm going to rate season 2 and 3 together because I feel it actually works better as one complete season instead of two separate seasons.
I think season 2 and 3 hits all the relevant story points. This is a story about the character Gi-Hun. It is a sad story which poses some important questions about ethics and morality in human societies. Seasons 2 and 3 had high internal consistency related to what was established in season 1.
Even more wonderful characters were introduced in these two seasons and Gi-Hun continues his emotional journey through this nightmare world.
The same high quality and recognisable look and feel is continued for these seasons.
The story of Gi-Hun is masterfully told and when he encounters other characters like Il-Nam and In-Ho, these encounters lead to a satisfactory expansion of his story.
Even though I feel there was a tiny gap to create an even more impactful story, all the expected story points were completed to a satisfactory level and scope, consistent with what was established in season 1. One could perhaps ask the question, does season 2 and 3 really contribute to the story? What was introduced to uplift the story with season 2 and 3. For me I think that Gi-Hun's story is more complete, thus season 2 and 3 does indeed have value.
The themes and ideas continue in a similar way as it was presented in season 1. Somehow I wonder if a little more could have been said by the writer about these things, but I believe the writer is satisfied with what is conveyed through all the seasons.
This includes the presentation of believable characters, as well as character development and character choices..
The audio and visual aspects and how it contributes to an appropriate atmosphere. The look and feel and production value as a whole. Can you easily associate and connect the ambience to the story or theme?
The quality and methods of storytelling. In other words, HOW the story is told.
The quality and believability of the storylines. In other words, WHAT is told.
The themes and ideas that emerge by telling the story.
