Sometimes I read these reviews and I wonder if I even saw the same movie as some of the other reviewers? I am not sure what those five-star reviewers saw, but it is not the tedious, lifeless dirge I viewed.
It is always challenging to adapt Ellis' novels to film; he walks the fine line between pop fiction and post modernism and it doesn't translate easily from the page to the screen. Rules of Attraction was probably the best conversion, although American Psycho wasn't too shabby. I liked Less Than Zero the best, but that doesn't necessarily mean its the best translation and frankly, it was the first, so there's nothing to judge against.
If the Informers seems disjointed, it should; it is actually a collection of short stories. According to Wikipedia: "Ellis's collection of short stories, The Informers... contains vignettes of wayward Los Angeles characters ranging from rock stars to vampires, mostly written while Ellis was in college. Ellis has said that the stories in The Informers were collected and released only to fulfill a contractual obligation after discovering that it would take far longer to complete his next novel than he'd intended." This tells me 3 things: 1) the movie is disjointed and dissassociative because basically the screenwriter tried to pound vignettes into a cohesive narrative, 2) the stories themselves were far from BEE's most polished work and certainly not reflective of a matured talent and 3) the book only got written to get his publisher off his ass. So no wonder the movie is so overwhelming.
To give the devil his due, it is beautifully shot and full of pretty actors and actresses with some name recognition and reasonable acting chops. But it is just so damn dull and plodding. The characters give you zero reason to like them or be invested in them and the stories just seem to go nowhere. Like much of Los Angeles, this movie seems to be obsessed in looking great without actually having an substance and looking busy without actually going anywhere.
As far as it's "accurate depiction of the 80's" as someone who actually grew up during that time, I am more likely to champion 'Stranger Things' or 'Adventureland'. While BEE may be able to capture the zeitgeist of a very small, very elite group of individuals, the vast majority of us never looked that good, snorted that much coke, and spent that much time and money being bored with life as the characters in this flick.
