BTW Is Cameron ever going to make those Avatar sequels? It's been nearly five years since the the movie came out, and that is not a good sign for a possible franchise.
I'm kind of afraid Battle Of Five Armies is going to ruin the whole Jackson LOTR franchise for good:

Fortunately I have never seen the last two Hobbit movies, but I think the main problem is that you can't make three movies out of one book. LOTR at least made sense: it was split into three books in 1954, and thus Jackson made three movies. I guess as long as Jackson doesn't alter the actual Tolkein books, we shouldn't get too mad about his film adaptations.
