SPOILERS, SO MANY
The deaths were shocking when Kili and Fili are dispatched I swear i cried. Tuareg is genuinely distressed by it. The amount of death is on par with LOTR. The most interesting I noticed were the apparent parallels between Tauriel/Kili and Thorin/Bilbo. Might just be my fanon goggles, but it was there.
In the end Legolas leaves his father on what appears to be a final goodbye (I'm pretty sure Thranduil is off to the grey lands, by the finality of their conversation) also Thranduil sends Legolas to find Aragorn so we know where that ends. Thorn and Legolas fought together foreshadowing him and Gimli. Thranduil turned out to be a pretty good dad actually and tells Tauriel loads of nice dad stuff. Gandalf takes Bilbo home where we meet the real villains, forget Sauron there is only one true evil and that is the...Sackville-Bagginses.
So that's it a fitting end to a beautiful saga. All in all it reminds of Samwise's speech from LOTR "It's like in the great stories Mr Frodo, the ones that truly mattered, full of darkness and danger they were" (FULL SPEECH HERE) Because thats what happened It was filled with darkness and danger but light must come. ThankYou Peter Jackson, It's been incredible.
