Avatar!! Its story, characters, special effects and soundtracks...but in particular for the themes that it shows: the human's arrogance against the Nature and its inhabitats, the importance of respect and tollerance with the things, the people and the other lives that are around us, and more...I love it! XD
+++ Biutiful +++
because it's beautiful
The Noah´s diary, the best romantic film I´ve ever seen.
The Lord of the Rings Trilogy (Gets better with every movie till the end) followed by Batman Trilogy (The Dark night was best) and then The Matrix Trilogy (but ending ruined the almost perfect movie)
twiglight , very romantic
