Saw it yesterday with the fam... Loved it.. It was as I expected it to be - while more kid friendly, it was a lot of fun and didn't seem to be almost 3 hours in length.. Very excited for part II..
On edit: So since it's been so long since I've read the books, I couldn't answer my son's question about Moria.... So after the battle of Moria, the Dwarves re-established a settlment there, only to have it overrun again in the years prior to the LotR trilogy? My son was wondering why Gimli didn't know that his kin had been killed off by the goblins/orcs... So I told him that I was assuming that after the battle where Azog was injuried the Dwarves took it over for a while, but were killed off sometime after that... No clue as to how or why Gimli didn't know about it..
