Netizens on Reddit and Twitter were mostly satisfied with the ending, and gave these valuable points to understand Erya:
The meaning of the Lord of Light resurrecting Beric six times is not for him to kill the Night King, but to survive to save Erya from the fire and water, Melisandre just reminds Erya how to respond to the god of death (indirect help) ;
The entire section of hiding in the library is only to pave the way for the final blow, in order to show how quiet Erya can be as an assassin (the first episode of this season is in the Godswood, she is in the snow came behind him without noticing it);
Good teacher: Syrio Forel, taught Erya the most basic and important swordsmanship, and guided Erya to think like a samurai: have sharp perception, graceful actions and learn to control fear, and the phrase "Not today"
