It was literally two comics, actually But if the scrawny little Hobbit book warrants 9 hours of movie, then I guess DOFP deserves 4 hours. I do hope Jean Gray is here is some capacity, though I'm kind of indifferent as to who plays her so long as it is played well. Famke is a bit old now relative to Jean's age in any of the comics I read.
Considering the majority of the hobbit film is incredibly accurate to the book and that the appendices, and unfinished tales are used to flesh out the happenings such as Gandalf and the White Council's assault on Dol Guldur, it isn't surprising at all that 3 filns can be made. Middle earth has a huge offering of information.
But are you seriously comparing two dinky comics to a full novel? You can read 2 comucs in about 20 minutes, and that is taking the time to admire artwork.
