CheckSuruWayo/Less Than Zero

Less Than Zero is a 1987 American drama film very loosely based on Bret Easton Ellis' novel of the same name. It received mixed reviews and the author of the novel initally hated the film due to it's differences.

Plot
Clay Easton (Andrew McCarthy) is a straitlaced college freshman on the East Coast of the United States, who returns home to Los Angeles, California, for Christmas to find things very different from the way he left them. His high school girlfriend and now model, Blair (Jami Gertz), has become addicted to cocaine and has been having sex with his high school best friend, Julian Wells (Robert Downey Jr.). Julian, whose life has gone downhill after his startup record company fell apart, has become a drug addict. He has also been cut off by his family for stealing to support his habit and reduced to homelessness. Julian is also being hassled by his dealer, an old classmate named Rip (James Spader), for a debt of $50,000 that he owes to him.

Why It Sucks

 * 1) The story feels like the most melodramatic anti-drug PSA since "This is Your Brain on Drugs".
 * 2) This is most apparent in the scene where Julian dies from an overdose since it comes out of nowhere so it comes across as totally forced and the fact it didn't even happen in the novel.
 * 3) Most of the acting is really mediocre with some exceptions (see redeeming quality #1) and a lot of people, including the author believe it was miscast.
 * 4) In an attempt to change the "slice-of-life" storytelling, Julian's addiction which was just a subplot in the source material become the main plot of the story even though it was just one of different things Clay experiences in the book.
 * 5) The Clay in the film is a completely different person in the film as he is now a anti-drug, stereotypical "good guy" protagonist which was basically the opposite of how he is in the novel.
 * 6) The film tries to be too sentimental and emotional which was often criticized for being "sanitized" compared to the book.

Redeeming qualties

 * 1) The performances of Downey Jr. and James Spader is actually really good.
 * 2) Julian is an empathetic character.
 * 3) It was one of the few films at the time which focused on the decadent youth culture of Los Angeles in the 1980's, something that even Bret Easton Ellis praised.

Reception
The film earned mixed reviews and has a Rotten Tomatoes score of 52% and 63% from critics and audiences respectively. It has a score of 6.4 on IMDb.
