I am a HUGE Tolkien fan. So as you can imagine I saw The Hobbit Battle of Five Armies (BOFA for short) a few days after it came out and I loved it (even though it did not stay true the the book)! However it made me sad. I walked away as The Last Goodbye was playing almost crying. Why you may ask? Because Thorin, Fili, and Kili died? No sir! I walked away in sadness for 1 reason and one reason alone...
What next? There is nothing left. LOTR has already been made. And I don't think you can do a better remake better than Peter Jackson's movies. So this is the end except for 2 options.
1- Silmarillion TV show
2- Children of Hurin movie
Now for those of you who don't know, the Silmarillion is a book about the creation of Arda, a mystical land with three continents, the history of which you can find here http://lotr.wikia.com/wiki/Arda. Now this would be an incredibly boring series and would require lots of creative license which I do not stand for. I prefer to stay true to the book.
I do not know much of the second option, Children of Hurin. From my research it would make an interesting movie. However I believe it would have trouble getting fan backing.
