Yeah, there's just no way a credible review of anything without imparting your own bias, opinions or politics into it.
Yes, if that political viewpoint flows organically from the review. But this was not the case with this review. He spoke about the movie, and, whatever you may think about "universal health care in America" the controversy was alive at that time, and his little Democratic leaning jab at the end had nothing to do with the film itself. and I can cite a few of his other reviews that did the same.
Don't get me wrong, I am a huge
Ebert fan. i am saddened by his death. He was a master writer. But he did put his personal politics into his reviews in the later years to actually make some kind of statement that went beyond his actual job description.
