Uno! has some good songs (Nuclear Family, Stay the Night, Let Yourself Go, Rusty James) and it's short enough to not make you turn it off and Dos! is pretty terrible. Tré, despite its middle section lacks punch, sounds like the best of the trilogy and the natural evolution from 21stCB, although it's nowhere near American Idiot. I'd suggest to skip Dos! entirely and listen to the other two.
Thanks for the suggestion. I haven't really
listened to Green Day since Warning, but I did listen to pieces of American Idiot and 21CB... I like their older more aggressive "punk" sound than the softer pop punk stuff they've done recently, but I'll check out Uno y Tre
