I haven't read his review of Juno, but Roger Ebert is pretty much my go to guy just because I've become so familiar with his reviewing style over the years. There are times when I completely disagree with him, but I don't find him to be the kind of reviewer as cultural weather vane, generally. When Reservoir Dogs came out for example, I think he gave it 2 stars and said that Tarantino could make a better film someday. He hated David Lynch's movies for years, but came around for Mulholland Drive. He's loved movies that I can't stand, but he's like an old friend who's taste I've grown to understand over the years. His recent medical problems might have an effect on his judgement when it comes to movie reviews of Juno, though, who can say. If you're trapped in a hospital maybe Juno's a welcome departure.. His standing as a class act is still firmly set in stone in my book, and I hope he hangs around to enjoy movies, because I feel like if Ebert's not around to enjoy a good movie one day, I'll be a little bit sad seeing it without him. And also, he kicked Oprah to the curb, so you've got to respect that kind of taste.
