I think Key and Peele are creating a form of comedy that is uncommon and well needed. Like the "Chappelle show" before this, Key & Peele tackle issues of race, stereotypes, and cultural problems in a humorous light. But unlike the "Chappelle show", the punchlines often go in a less obvious or slap-stick direction. (I would like to list examples, but I think you are better off just watching the show.) Though the punchlines don't always work, the overall skit concept still resonates. Key and Peele have a way of presenting their concepts in a way that don't require a solid punchline to drive the point home. A final note, and my personal preference, is that Key and Peele also have a love of cinema. Thus, many of their skits play off famous movies, which I personally enjoy quite a bit. Overall, "Key & Peele" is probably not gonna start a cultural revolution, but it sure will help clarify the truths and flaws of stereotypes.
