Controversial documentary filmmaker Michael Moore slammed President Barack Obama during a discussion at The Hollywood Reporter's video lounge at the Toronto Film Festival Wednesday, expressing a "huge disappointment" with the legislative accomplishments of the politician. 

"When the history is written of this era, this is how you'll be remembered: He was the first black president," the progressive documentary filmmaker said about the president's legacy.

"OK, not a bad accomplishment, but that's it," the director said. "That's it, Mr. Obama. 100 years from now: 'He was the first black American that got elected president.' And that's it. Eight years of your life and that's what people are going to remember. Boy, I got a feeling, knowing you, that - you'd probably wish you were remembered for a few other things, a few other things you could've done."

"So, it is, on that level, a big disappointment," Moore said.

Although Moore, known for his political activism, strongly supported Barack Obama for both of his presidential campaigns, issues like the NSA leaks, campaign financing and drone strikes has left him disillusioned with the Obama administration, he said.

In the video interview, Moore was asked what he thought about Obama' handling of the situation in Detroit.

"You did not save Detroit. You saved General Motors. You saved Chrysler," Moore said. "Detroit at this point would stand a better chance if they were an Iraqi or Syrian city - in terms of getting some sort of help. I think Obama, sadly, you know, has done many, many good things, but he's also been a huge disappointment.

Cash-strapped Detroit, which became the largest U.S. city to ever file for bankruptcy protection last July, began to recently disconnect water services for all the households that were unable to pay their bills for two consecutive months.

"When you start turning the water off in 150,000 homes because they haven't paid the water bill? You have that many people without water? You start turning the streetlights off so the city is dark at night? A large American city in pitch blackness? Is this some sort of social experiment they're trying to see, 'How far you can push the poor?'" he continued.

Additionally, Moore did not seem confident that any big milestones will be achieved during the rest of Obama's term, AGC.com reported.

The documentary filmmaker appeared at the Toronto festival for a screening of his acclaimed title Roger & Me, which is celebrating its 25th anniversary this year. The film, centered on GM's then-CEO Roger Smith, kickstarted Moore's career in creating controversial political documentaries, including "Bowling for Columbine", "Fahrenheit 9/11" and "Capitalism: A Love Story," according to The Hollywood Reporter.
