Please give me your thoughts about what I think was wrong with this, thx

There was much I liked about this movie - at the end, Madea is telling one of the sisters that forgiveness is to help yourself, not the evil-doer. Unfortunately, Madea was speaking too fast, so a lot of people probably missed that.

(a) What I didn't understand was (and didn't think it was funny) was why was she so mean to Mr. Brown?

(b) when she was giving the whole family the lecture, I get that she didn't need an "Amen" from Byron, but he was trying to get his life together with a job. Yet she chastised him for not having one, having gotten fired when that wench Sabrina hauled him in for back child support. SHE was the one who would have mouthed off and deserved to be slapped! Yet uncharacteristically, she sat silent. It would have made more sense, to me, if Madea told Byron that "you took what easy" (sex with Sabrina) and now you got a kid. Paid a big price for a few minutes of fun......" Certainly Madea would know how hard it is for anyone with a prison record to get a job, especially a black man so slamming Byron for what Sabrina did made no sense.
