To be honest, I've only watched about one episode so far, so I haven't really delved into the content yet, but the sound quality is recorded at a level similar to a cassette recorder from the 80s. I'm not sure if it's due to the recording quality or the actual speech, but instead of standard Korean, there is a very heavy Yanbian (Korean-Chinese) dialect. I'll have to watch more to see if the content itself is substantial, but looking at the recording issues alone, it feels like they put in zero investment—it's worse than a basic laptop recording. Selling a video like this feels very insincere. Furthermore, despite calling it the 2026 revised edition, the content inside is using GPT-4o.
