I am writing what will potentially be a long series of fantasy novels, a lot like Dragonlance I hope. I also hope that one day I will have films made of them.
There is so much to fit into a couple of hours that a lot of it can't be included. Only the major parts can really be considered.

I tried to read Lord of the Rings. I got to the council of Elrond and gave up. Yes, it's considered to be the most epic fantasy book to date, but it takes so long to get into that I got bored and gave up. The films, I can watch. However, the book is so long that the Peter Jackson had to cut an awful lot out of the films, and even then each film is 3 or more hours long!
