It's situations like this (and Godzilla) where I wish I had enough skill and motivation to make "viewer's cuts", where it works opposite of director's cuts, and takes out all the filler and results in punchier movies.
The first Hobbit dragged a bit in the middle, but I didn't think the second was too terrible - I'm glad Bard and Smaug got expanded roles, for example, and having a badass girl character would have been great if they didn't use her to hammer in romance. I'm sure actually showing the battle of five armies will also be an improvement over the book irritatingly skipping over it entirely, and the dwarves having involvement with the town attack should also make things feel more interconnected than when they just sat around in the cave like useless lumps wondering "hmm, where did the dragon go?" in the book (like how them going to help Bilbo was better in the second film than in the book, where they sat around in the cave like useless lumps wondering "hmm, hope he's not eating our burglar down there lol").
