I never reallly got that feeling before. Normally I'm like a normal person and I'm just sitting lazily in my theatre seat.
UNTILL......
The battle at the gates of Mordor in RotK. When Aragon's doing his speach and the gates are opening, the music is glorious, and Sam and Frodo are on the slopes of Mount Doom. All of that just stirs your emotions so that by the time Aragorn says "for Frodo" the only thing stopping me from getting up and following the charge is I'm afraid of getting kicked out of the theatre.
To me that is my favorite scene. Viggo has so much charisma and the fact that the hobbits are the first to follow give it heart.
can't wait to watch it a home.
