AHHH!! I can't wait till it comes out!

I think it makes sense that the second of the trilogy would be the darkest. If you think about other trilogies, such as Star Wars, The Lord of the Rings, etc. the second of the series is the usually the darkest and ends on the most hopeless note. Because at first you get know the characters and they maybe win a battle but not the war and it's all fun and good, but then in the second episode a beloved character generally dissappears or dies, someone is frozen in carbonite and Boba the fette is all up in your face with flame throwers and talking about his car payments? The thrid of the trilogy is where the miraculous happens and in a bizarre twist of fate giant eagles swoop out the sky and the peace is brought back to middle earth.
