6 things we want "The Hobbit: The Battle of the Five Armies" to do.

1) Tie in Gandalf's quest with LOTR. 
In Desolation of Smaug, Gandalf confronts the necromancer, who reveals himself to be Sauron. This is a pretty big deal, because it means that he is back, even though can not take his full form yet. The fight scene between Sauron and Gandalf was awesome, but there is one problem. I'm not sure how they are going to properly tie it in with "Fellowship of the Ring" the first movie in the LOTR trilogy.
In Fellowship, Gandalf has his suspicion that the Dark Lord Sauron might be returning, so he has to go of and do research for months. He then comes back to Frodo with the quest to get the ring to Rivendell. If he meets Sauron in Desolation of Smaug, how can he doubt that he came back? He would not have to go do research, because he has already seen him. Hopefully Peter Jackson does not look over this fact and manages to tie it in. Gandalf's story in "Desolation" ends with him being pinned against a wall, looking hopeless. Perhaps in the movie he will get his memory erased, or maybe the Necromancer is not actually Sauron. We will have to wait and see.

2) End Kili's relationship with Tauriel on a friendly note. 
I didn't mind the relationship between Kili and Tauriel in Desolation of Smaug, but if it ends with them marrying and having a bunch of dwarven-elvish kids, that will be ridiculous. I think the filmmakers are going a little to far with their "love story" and I hope they end it in Battle of the Five armies, and the two don't end up together.

3) Make the battle epic. 
This is something that Peter Jackson proved he can do. Look at the "Siege of Helm's deep" in "Two Towers" or the battle of "Minas Tirith" from "Return of the King." Long story short, those battles are awesome. What worries me, is the actual FIVE armies. I have my fingers crossed that Jackson is going to be able to show us a fair bit of each army, and still make it interesting and flow well. I'm sure that it will be at least great, but I want it to be amazing.

4) Make it about the Hobbit. 
In "Desolation" we saw a shift of gears. Bilbo stopped being the main character, and Thorin Oakinshield took over. I think it was a good choice for the second film (just like Aragorn and co became the focus of the two towers), but I wish that in the third film the story centres around Bilbo again. Just think about it, this huge war going on between all these warriors, and a little, defend less hobbit stuck in the middle. I'm not saying that Oakinshield should be shredded from his portion of the story, I just hope that in this film we concentrate on concluding Bilbo's adventures as well as the dwarves' quest to retake their realm .

5) Finish off Smaug. 

Desolation ended on a cliffhanger with Smaug headed towards Lake Town to destroy it. I hope that Bard gets rid of the Dragon in the first 20 minutes of the movie so we can concentrate on the battle for a longer time. Most likely Bard will shoot the black arrow at Smaug, but imagine how cool it would be, if he charges at this huge dragon with the arrow in his hand as a spear, and stabs him right under the wing in mid air. I know this probably won't happen, but Imagine how cool it would be. 

6) Give the sense of Danger. 

The dwarves are pretty much invincible. Nothing has ever harmed them, except for the arrow that pierced Kili. I loved the barrel scene and all, but seeing Bombur jump around in his barrel and take out a dozen orcs, makes the dwarves seem like superheroes. Why should you worry for characters who are practically invincible? I don't want half of the Dwarves to die in the movie, but at least show some injuries, and actual danger. Don't just have the 12 running through an army of Orcs, taking them down carelessly like Gimli did in the battle of Helms deep when he and Aragorn jumped on the bridge.
