One scene I absolutely adored as well as the ballroom part was the part where the Beast tell Cogs worth that he loves her. It was so romantic I could have cried.

I agree ^^
That is a very romantic and powerful scene

I wouldn't say its my Favorit scene, but I liked how he struggled to say "then Du must go."
The part where the Beast eyes roll back, the dying part, that was sad. How Belle holds his hands and suddenly they have no Mehr motion. and of course, when Belle says "I Liebe you."
