Just for fun, here's the last few for 2005

the most boring movie you can think of Domino, because of it's pseudo-drama and ridiculousness.

the most exciting one War of the Worlds proved to be pretty exciting thriller-wise.

the most disappointing one Kingdom of Heaven, while good wasn't the great film I originally expected

the most poignant Last Days and Broken Flowers

the scariest n/a

the funniest The 40 Year-Old Virgin

the sexiest (porn doesn't count) Sin City

the stupidiest The Longest Yard, Domino, and The Legend of Zorro
