Loving the idea, meeting new people and of course it's beneficial to minimize your accommodation expenses :) I believe that the only chance to get deeper in the country's atmosphere is to get to know the people who live there.

Tron Legacy is number 1 for me! Few words about movies: good movies is a rarity today. Cool special effects can't make movie great if scenario is poor. Such movies like "Troy", "Godfather", "Legends of the fall" will be best forever.
