Mark Ruffalo's A-list acting has been recognized through his 3 Oscar nominations over the years, but they were all for best supporting roles, and he has not won any of them. Until "I Know This Much is True," I've dismissed him as an actor just playing roles that disappear into the sidelines, with his soft-spoken unassuming demeanor. That subdued demeanor works well in this outstanding show. You can feel the character Dominick's pain oozing out of his raw emotions, similar to Joaquin Phoenix's Joker, except here, it doesn't seem like acting. Sometimes I wonder, is Mark Ruffalo himself really this sad? Give him a Golden Globe or Emmy for this role already!
