Cranberry sauce - yes or no?

Cranberry sauce is staple at the Thanksgiving table. Some people make it from scratch, with chunks of fruit in it, actual cranberries and even apples. Others LOVE, and I mean LOVE that gelatinous blob that comes out the exact shape of the can it's in. They slice it and people gobble, no pun intended, it up. Cory has actually NEVER eaten either kind and both just seem gross to her. Is it a necessary dish to make Thanksgiving? Why do we only eat it at Thanksgiving? Why is one jelly in the shape of the can and the other a beautiful bowl of what looks like candied fruit? PLEASE solve the Great Cranberry Debate and share your thoughts.
