The fact that Jeod or Teirm never appeared and he was the catalyst for Angela and Solembum, the whole journey to Dras Leona and the Ra'Zac and a lot of character development for Eragon and Saphira while they were forced apart, not to mention Rorans story in 'Eldest' was one of the biggest and most significant omissions from the film. Such a shame they left that out.
