I've never found Ninrod. to be anywhere near as all over the place as people say it is. There are obvious outliers--KFAD, Take Back, Good Riddance--but on the whole I think the songs have a very cohesive sound. They're all classic melodic four-chord Green Day, and the production and instrumentation don't vary incredibly from song to song. If anything Warning is far more a clusterfuck in terms of consistency than Nimrod--within six songs you have a Kinks ripoff, a rockabilly number, a few classic Green Day songs, and a goddamned Russian waltz complete with a spaghetti Western bridge. Compared to the first half of Nimrod which apart from the inclusion of strings and brass on Hitchin' a Ride and Last Ride In is pretty cohesive.
