It's been a great year for documentaries about business and innovation.

In 2018, documentary filmmakers tackled complex, important subjects ranging from blockchain technology to the #MeToo movement to the corruption of the American dream. Whether you plan to spend the holidays reflecting on the past year--or trying to escape it--there's a strong group of business docs you won't want to miss.

Here are the eight best business documentaries of 2018.

1. Paris to Pittsburgh

In the wake of President Donald Trump's decision to exit the Paris climate agreement, this documentary follows the individuals fighting the impacts of climate change in their own backyards. The film also focuses on small-business owners in Iowa who have embraced renewable energy to keep their businesses competitive and a nonprofit in California that helps businesses hire former inmates trained in solar panel installation. Paris to Pittsburgh premieres on Nat Geo worldwide on December 12.

2. Generation Wealth

Acclaimed filmmaker Lauren Greenfield's latest documentary makes the case that America's obsession with wealth has corrupted the American dream. The film looks at both super-rich hedge fund managers and those struggling to make ends meet, serving as a cautionary tale for entrepreneurs--and everyone else--that making money your top priority is unhealthy and unsustainable. Generation Wealth is available to stream on YouTube, GooglePlay, and Amazon Prime.

3. Trust Machine: The Story of Blockchain

Stories about blockchain technology were everywhere in 2018, but filmmaker Alex Winter's documentary is a comprehensive account of the digital ledger that records cryptocurrency transactions--and holds the potential for so much more. The film also follows hacktivist and blockchain expert Lauri Love as he fights extradition and tries to show the world that blockchain technology can be used for noble causes like fighting hunger. Trust Machine is playing in select theaters and will be available to stream soon.

4. Science Fair

Winner of the audience award at the Sundance Film Festival, Science Fair follows nine high school students as they compete in the International Science and Engineering Fair.

5. Won't You Be My Neighbor?

As the cardigan-clad host of the renowned children's show Mister Rogers' Neighborhood, Fred Rogers revolutionized educational TV, forging millions of meaningful relationships with viewers through his unique understanding of the link between emotion and learning.

Won't You Be My Neighbor? is available to stream on YouTube, GooglePlay, and Amazon Prime.

6. Seeing Allred

Women's rights attorney Gloria Allred has been fighting injustice against women for decades, but the rise of the #​MeToo movement has helped create a sense of urgency around fighting sexual harassment and abuse--in and out the workplace.

Seeing Allred is available to stream on Netflix.

7. Mercury 13

In 1961, as part of a privately funded program, 13 women took the same physiological tests that NASA used for spaceflight, only to have their hopes dashed when a team of men became astronauts.
