and jack being helpless i also found it sad when all the guardians think jack betrayed them

It was sad because I had JUST placed him as my favorite in the movie, and had hoped he would kind of save the film for me. After his funeral confirmed it and Jack was moping at the window, all I could think was "...What?! No! He'd BETTER come back!" The fact that he's a sleep-based guardian meant there was no sense in NOT reviving him. How do you not have SLEEP?! So until his revival, I was just a little sad and upset that I wouldn't be seeing him until the climax (if he came back).

5.Kid's Losing Faith Tooth

I was nearly crying when Sandy got hit and started to disappear...

I also agree with peterpanreal's choice of order.

I didn't expect his death, I found him really lovable and appealing on the first moments of the film and with Sandy just being gone it was just sad, adding to my grief is because he was the Guardians of Dreams and being fond of dreams myself and seeing the very source that gives these to us being consumed with darkness is kinda hard to take in. (I wonder what might've happened if he was really gone, geez, i hate that thought)

All of them are sad :( I couldn't pick which one was the saddest so I made this one up

^ That...what?

It was one of the most dramatic scene I've ever seen in an animated movie. Sandy died like a gladiator, surrounded but enemies, cowardly backstabbed. He didn't give up until the very end. Such an intense pathos.

Very sad!! I would say......:-(

He looked so sad.

Me: Stop scaring me, Shenny -_-
Shenny: Oh.... :P

Pauline: SHHHH!!
Shenny: Nah....
Macey: Um guys, we're in the theater
Jasthine: Shenny, stop
