Butchered in the editing room
The art direction, costumes, decorations, effects, etc. The entire technical side of things is beautiful, as is usual for Scott.
But despite being two and a half hours, the story has no real depth to it. The characters are all underdeveloped, every single stop on their journey is just breezed through to the degree you barely understand the motivations and psychology of the characters.
For example Sigourney Weaver has like three minutes of screentime - there is no way her role was not completely edited out, otherwise it would make no sense to get such a known actress.
This has happened many times with Scott - he really should have either released a 180 minute version, or adjusted the script so it can be more coherent in 150 minutes.
At the end of the day, these half-baked cuts do not satisfy anyone - casual fans will find the movie too long, impersonal and uninteresting, while movie buffs will find the movie too empty, too brief and disjointed.
Laura:You left a dead prostitute buried alone in the desert?
Kyle:She's not alone.
