This film was okay. It reminded me of when someone would copy your homework in school and change it slightly so the teacher wouldn't suspect anything-- except ESPN's version was better.
I'm guessing ESPN had a larger budget maybe? It was edited better and Vince Vaughn's narration put it over the top. This film has high profile interviewees such as President Barack Obama and Bill Murray... but that's about all it has better.
If you are looking for the best documentary about the '85 Bears.. watch the 30 for 30.
