I got the vibe that the author didn't like Elsa, or rather, didn't find her a strong female character because she has personal issues and insecurities.

"This is not a strong woman. This is a frightened, repressed, vulnerable woman who starts running at the beginning of the movie and doesn’t stop until her sister literally turns to ice in front of her."

Oh so people who are frightened or repressed can't be strong now? If you show any emotions you're suddenly horribly written??? Is that right? Because that's the vibe I'm getting.

Set yourself on fire and ask Elsa to douse the flames for you. Oh wait, she probably wouldn't. Because she's not a strong woman.
