YMMV / Legacy (Frozen)

• Funny Moment: Early on Eugene mentions to Elsa that in the rowdier bars people have been writing smut about her and Anna following the 'act of true love' that saved her. In the penultimate chapter after beating Maleficent, Anna finds one. Elsa's only reaction upon reading that she and Anna did something lewd as an act of true love is to comment that the artwork is good.
• Nightmare Fuel: The entire conversion process which is done by taking your worst memories, then making them even worse, and then hitting you with the full emotional impact of those events repeatedly until you 'voluntarily' agree to serve as a Heartless. Specific examples from Elsa's nightmares are Anna not thawing and her committing suicide by Hans at the end of Frozen, her killing Anna when they were children, and numerous others. It's mentioned that besides many deaths of varying types, there's also emotional and sexual horror mixed in.
