1. Big epic scale visual effects in 3D is not what drives people to theaters. 2. Do not hang the success of your sci fi/fantasy epic on the shoulders of a child actor 3. Do not pander to small children with cute for cuteness sake. Cute can misfire. It can be annoying. It can be jarring. It can be jar-jarring. 4. Story matters. 5. Having characters that people can like and relate to matters 6. Find a writer with a sense of humor. 7. Give your actors room to act. Collaborate with them in the acting process. 8. Don't have the same guy who oversees the budget, the licensing, the merchandising also oversee the creative process. Anything else?
