sleeper is hilarious but it's also pretty dated, bananas was goofy in a good way but also very dated, what's up tigerlilly is unwatchable, etc.
however--- bullets over broadway came after his late 70s/early 80s golden era but it's still great (i think it was right before deconstructing harry).
from his new stuff i've loved midnight in paris, match point, sweet and lowdown, and... what else was there... oh, yes, barcelona! i mean vicki cristina barcelona. gorgeous cinematography on this one, a lush yellow palette. great cast too. plus, your trip!
