I have too many favorites but here's the top 10 movies/series from the top of my head:
10) To Train your Dragon

9) Cloverfield

8) Iron Man II

7) Hellboy II

6) Dark Knight

5) Serenity

4) The Incredible Hulk 2008

3) Matrix: Revolutions

2) Scott Pilgrim vs. the World

1) Spartacus: Blood and Sand
You all should watch these with the Buttkicker LFEs (or any other ground pounding Tactile Transducers). Spartacus is my personal favorite so far and I use this everytime I get to demonstrate the Buttkicker experience to my friends who never get to experience it!!
In addition, thank you all for listing your personal favorites because I plan to watch them with my buttkickers in the future.
