It seems worth mentioning that anyone’s opinion of a biopic will definitely depend a lot on how well that person knows the source material. The more one knows, the higher the expectations.
To put it candidly, I knew virtually nothing of Tammy Faye Baker, other that she, along with her husband, was one of the more popular televangelists of the 1970s and 1980s (just before my time). At many points of The Eyes of Tammy Faye (based off of a documentary from 2000 of the same name), I realized they were the reason I would see other televangelists as a kid when I would be flipping through channels early Sunday mornings (paving the way for the likes of Joel Osteen).
