Oh, no. NononononononononoNO. This has to be the most misleading movie trailer I have ever seen. At least, I certainly hope it's misleading, because that is NOT the Bridge to Terabithia that makes me bawl every time I reread it.
Seriously, people are going to take children to see this thinking it's some Narnia rip-off and then EVERYONE WILL BE TRAUMATIZED FOR LIFE!
