His work out of Lotr? The acclaimed Dead Brains? King Kong? No, outside LoTR Jackson is not really a fine director.
No sense of timing and chronology? The movie has a poor rythim. While traveling by a giantic world, the characters meet each other as if that world is my yard. There is the clumsy sequences of epic battle and sentimentalism with side stories like Aragorn love story.
Acting is not a paramount on Fantasy is such silly claim I will not bother to list fantasy good performer. I will just point that if you have to appeal to genre to justify poor acting, then you just agree the acting is poor.
As the dialogue, did you even finished the book? And sorry, the dialogue is even poorer. The comedy of Gimili legolas is awful.
LoTR main villain in second movie vanishes and his magical item appear out of nowhere. It is a major continuity mistake, not some goofy. (Two claims you already agree, and you just called they are not true. Kaput on you?)
The battles are not "few" and the special effects show is all the time. I never said was poorly made movie for lack of money, but heck, congratulations, the majority of blockbusters are bad movies.
Considering LoTR is one of the most sold books of all time, his survival based on his academic wok and not on his novel is one silly claim. One of those you argue and mean nothing, as you cannot prove or sustain it.
So, let me understand... the acting is not good, editing is not good, your best defense is comparing to blockbusters and dialogues yoou consider bad... And yet the movie is good? So, good is when you suffer to watch?
