This dark deeply personal saga is about Joker's mind and how HE IS "ALONE" in a crowded world gone "MAD!"
His goal is to get to a place where HE can FEEL "SAFE"! AND, in the END... HE attains that goal... That "final" scene... (Go S@@ the movie!) "Solidifies" everything in a "NUT" Shell!
HE IS Finally "HAPPY" AND "FILL-FILLED" AND Proud of Himself... HE has "FINNALLY" Accomplished a "PERSONAL GOAL" That HE has set for Himself. HE IS Where HE Needs to BE... AND... Wants to BE... Thank You!
