I'm a huge fan of John Stewart and Steven Colbert. I've watched them for years, and I was a big fan of John Oliver on Stewart. After his star turn as Stewart's long-term sub, it was obvious he was ready for his own show. So now that he finally has it, I was eager to check it out. I don't have HBO, but I have watched a few segments online. I like it. I don't actually think it is as funny as Colbert and Stewart. But he has done something remarkable and unique. He is extremely funny and satirical, while at the same time being highly informative.
Ideally, one watches Stewart and Colbert with a solid, pre-existing understanding of the issues. Less than ideal, but better than nothing, a viewer clues in to an issue by watching them, and subsequently pays more attention to it. Their shows, as good as they are, aren't really a way to learn about an issue.Oliver's show, on the other hand, has high comedic content, but less than Stewart and Colbert. The difference is, his segments provide a complete briefing on a topic, while still being quite funny. So for many audiences, I think his show is amazing. It is like making vegetables taste as good as dessert.
