Well, I liked it in general. Overall is a nice movie. But there were two things really bothered me during all the film. First, the rythm/pacing of the movie, it starts REALLY slow, but then at some point it starts to rush. There were some scenes where you were thinking: "come on, that's not relevant at all, just move on to something interesting!" Then suddenly lot of events start to happen so quickly that you can't flavor them properly.
They should have shortened some pointless dialogues to extend other scenes
The second thing that disturbed me...may be Im wrong because I didn't read the book... but I had the feeling the film tries too hard to look connected to LOTR trilogy. I don't know, but there are some scenes that look quite out place, because it doesn't really fits THIS story, it looks like they added that to make it sure you relate it with LOTR. But as I say since I didn't read the books I don't know for sure if those scenes were actually on the book or were invented to the film.
Let's see here. A mere 13 dwarves, a single Hobbit and a wizard are gonna take back the dwarven stronghold that is infested with thousands of goblins/orcs? (I forget which is which). Yeah, those are REAL good odds, 15 VS thousands.
They don't want to take back a castle from orcs the orcs are just in their way. Is a dragon the only creature they need to kill to take back their treausre and country. Is 15 vs 1
BTW in LOTRverse goblins and orcs are the same, they just use one name or other depending on the ocassion. They are all "orcs" sometimes uses the word orc sometimes goblins. There are not really any significant difference between goblin and orcs unlike in other settings.
