Seems to be getting quite good reviews.
Discussion points, whether you've seen the film or not, would appear to be:
- Is the film too long?
- Are three films from such a slight children's book, too long?
- Why include Legolas when he's not mentioned in the book?
- Why invent the elf-maiden Tauriel?
- How sexy is Richard Armitage?
Those questions should not give rise to spoilers. They also ignore what a great achievement all these Peter Jackson Middle-Earth films are, even if there are a few dud notes.
