Everyone is excited about the visual, stunning nature of another James Cameron movie. The problem is where it is visually stunning. The movie lacks any true story it lacks any real depth and quite frankly it's just boring as hell may be able to felt differently if the movie had come out within a reasonable amount of time. Instead, Hollywood didn't want to do a sequel until frankly, they just realize they had no more ideas in the last few years they just decided to make sequel after sequel, screwing up sequels in general.

Poor writing. Still making the indigenous folks seem like they're just idiots.
