'The Dark Knight' 2005-12
The only trio of movies from the past 15 years I see fit to mention is the newest "Batman" trilogy. My reasoning for selecting these in particular, and not, say, "Lord of the Rings," is that "Batman" was firstly, awesome, and second, didn't put me to sleep. My generation's movie selection is sadly pretty pathetic, but this set certainly redeems some of that. But this set of films is enthralling, well done, visually impressive and the acting is absolutely incredible.
No one beats Christian Bale as the Batman, even George Clooney, which is saying something because I am usually a big George fan. There is no excuse for not having seen these movies. They are, by far, the best of all of the attempts to make "Batman."
