Not good news for Eragon fans

I was thinking about taking Sarah and Samantha to see Eragon over the Christmas break but it looks like it's getting panned by the critics. I have a feeling that my daughters aren't going to care and they're going to make me take them anyway and I'm going to have to watch a really bad movie. I can't even hope that it's better than what the critics say (as was the case with The Nativity Story) because I was bored watching the trailer.
