There are many fans that love the first movie and are now saddened that there might not be a sequel. There is so much mythology that has not been explored yet. The movie is so full of magic and hope, you can feel like a kid again when you watch it. We all know that it didn't do the greatest at the box office, but that shouldn't stop another movie. I believe that Rise of the Guardians could be a trilogy, and I think the fans think so too. We believe in you DreamWorks and we need you to believe in Rise of the Guardains again; bring the magic back again.
P.S If anyone knows someone from DreamWorks please show them this. Show them that fans really want this and care.
