So I'm looking for a work of art (painting, movie, literature, poem, etc.) from 1990 to modern day that has one of these traits:

- Feelings or intuition over reason
- Champions individual freedom and worth of the individual
- Civilization as artificial
- Urban areas are a detriment
- Negative industrial advances
- Seek beauty of nature
- Nature as a path to spiritual development
- Preoccupation with madness or dark sides of the human psyche

Basically American Romanticism and transcendentalism. Any ideas?

After 1990? That's pretty limiting!!

Choose one and start searching his/her works.

I can't think of any "back to nature" tomes I've read in the last few years. I'm sure there are some. Novels that do deal with the darker sides of human nature and the artificiality of modern society are many. Anything by Louise Erdrich might qualify. Richard Ford' LET ME BE FRANK WITH YOU (2014) fits; Jim Harrison's THE RIVER SWIMMER (2013); Jonathan Franzen's THE CORRECTIONS (2001); Viet Thanh Nguyen's THE SYMPATHIZER (2015) all might suffice (and all are very, very good). I can think of a couple of plays: CLYBOURNE PARK by Bruce Norris (2011) and AUGUST, OSAGE COUNTY by Tracy Letts (2008). Short stories: anything by Lorrie Moore (BARK, 2014). George Saunders' short stories, too. I don't know that this helps, but those are a few suggestions.

To find a work of art that aligns with the traits you've described, you can try several approaches. One way is to search for art movements or genres that reflect American Romanticism and transcendentalism. Another approach is to look into specific artists, authors, or filmmakers who are associated with these ideas. Here are a few suggestions that may meet your criteria:

Literature:
1. "Walden" by Henry David Thoreau (1854): Thoreau's book is a classic example of transcendentalist literature, emphasizing the connection between nature and spirituality, individual freedom, and the critique of modern civilization.
2. "Moby-Dick" by Herman Melville (1851): Although published before 1990, this novel explores themes of madness, the dark side of human psyche, and man's relationship with nature, making it relevant to your criteria.

Movies:
1. "Into the Wild" (2007): Directed by Sean Penn, this film is based on the true story of Christopher McCandless, who abandons civilization and embarks on a journey to find spiritual fulfillment in nature.
2. "The Tree of Life" (2011): Directed by Terrence Malick, this visually stunning film delves into themes of nature, spirituality, and the human condition.

Painting:
1. The works of Georgia O'Keeffe: O'Keeffe's paintings often depict natural forms, emphasizing their beauty and evoking a sense of spirituality.

These are just a few examples, but you can further research artists, authors, poets, filmmakers, and art movements associated with American Romanticism and transcendentalism to find more works that align with the traits you're seeking.
