Listen, why don't you try respecting that people's opinions are different than yours? And that it's perfectly valid to hold an opinion thats been given somewhere else before
And I do think Kate Winslet was more a Supporting Actress in The Reader, as I interpret the film as not being as much about her character as about Michael. The same could be said about many other parts, of course, but for me it wasn't a Lead Actress performance.
But each to their own, which you need to respect.
You're not the only one who thinks so either. Of the 10 awards she won for that part according to Wiki, 4 of them were for supporting actress including the Golden Globe and the Screen Actors Guild award.
