I enjoyed Tre a fair bit, but the other two were a bit dull I thought.
And I really like Warning, but I can see why it was less popular. It was less punky and had quite a different vibe, and at the time Green Day just weren't really in the forefront of public consciousness. They put themselves there again with American Idiot, which was not only a great album but also got a lot of hype going for being a punk rock concept album which is quite a rare thing.
