What it actually is
Billy Go has been publishing for over a decade and his beginner and intermediate playlists work as an actual sequential course rather than a pile of one-off videos. He is clear about pronunciation rules and sound changes, which most channels gloss over. All free on YouTube; he sells the Korean Made Simple books separately. Presentation is plain talking-head — no production polish, just a lot of accurate teaching.
