Exactly what it says on the tin - to a fault.
Don't get me wrong, I like it. However, towards the end 'The Hobbit: The Battle of the Five Armies' definitely begins to drag quite heavily - the impact of what eventually happens did not, to be honest, hit as strongly as it could've/should've. The pure action is good, but there's not much to remember about everything else.
None of the characters, with the exception of Richard Armitage (Thorin) and Luke Evans (Bard) I guess, stand out amidst the wall-to-wall battle. Martin Freeman (Bilb), Ian McKellen (Gandalf) & Co. are are of little importance really, which is a shame.
'The Hobbit' series, unfortunately, gets inferior as it goes by. Loved the first film, enjoyed the second but this third installment - while passable - leaves me with a feeling of wanting something else from it. Happy to have watched them though, I'd still recommend them for sure.
