The Hobbit Book vs Movie

As most fans know The Hobbit takes place before any of the Lord of the Rings. Whether it be book or movie. The Hobbit starts with Bilbo writing in a journal as an old man about his adventures of the youth. Though the book and the movie show many inconsistencies. Anyone who read the books can tell you this.
Of course to make a book that was little over 200 pages into 3 movies you'll have to add filler content that was not originally in the book.

The inconsistencies include:

• The white orc which was not mentioned in the book
• Bilbo is polite to the visiting Dwarves
• The Over Dramatized fight with the Goblin King
• The Elves did not delay the Dwarves in the book but they do in the movie.
• The Eagles, they talk in the book.
• The Eagles talk to the Dwarves after saving them. 

Of course, there are probably more I overlooked but those are a few. The movie is obviously a very interesting movie but it does have some inconsistencies. Though, they might have reasoning, making the movie more action packed, however, it probably didn't need to be made into 3 parts. It was dragged out more than it needed to be.
