Some people might think, "oh, this seems really good for black", but you have to remember black only has two corners. Black is potentially gonna have to capture the R4 stones, so black's lower right corner is about 13 points; the M4 stones aren't fully connected; and white has access to the right side.

White's kind of settled here; there's no way for black to continue attacking this group reasonably.
