Agreed. While I often disagreed with Ebert, and detest his politics, I hold his movie reviews in esteem because they are built on well-informed history and insights of movies developed over many more viewings than I have. You don’t have to agree with someone to respect him.
What I’ve always liked about Ebert as a reviewer is that he likes both art movies and fun movies. There aren’t many big time movie critics out there that would even admit to having watched a Russ Meyer movie, much less WRITTEN one.
