<< This describes how lame audiences can be.
The first time I saw it, the theatre was packed. As you'll remember the last scen is of Frodo and Sam looking toward Mordor about to cross the swamps (IIRC). Well the credits begin to roll and a lady stands up and says to her companions, "I guess they never made it huh?" She had no idea what she was watching..... >>
That was the best part!! As the movie ended, the folks who don't read books or know anything about the next two releases plan all go, "whaaaaaaaaat??????" Me and my friends cracked up! Almost as good as the whole audience simultaneously going, "eeeeeewwwww" when the lead orc's head got cut off.
