Extremely presumptuous of you to assume anything about my life experience.
I think Brooks did a terrible job in that scene and plenty of other people agree. You're not going to change anyone's mind by being condescending.
They're hardly being condescending, Mr. Homn. They're merely sharing an assessment arrived at through life experience. Anyone who's seen another person suffer an emotional breakdown of the kind Benny Russell had knows that Avery Brooks' acting was spot-on. That's not to say Brooks didn't have his "over-the-top" moments. He most certainly did; however, that scene wasn't one of them.
You're welcome to believe what you wish. I won't presume to know anything about your life experiences. I would caution you, however, that assuming you're right simply because other people agree with you isn't the best perspective to have.
