Here’s my two cents:

• I think this is one of the rare instance where we see fire being super effective against water
• I like the mother and daughter as much as the father
• I’m so glad to see Narnia being recognised as an isekai
• I’m even more glad to see how the mother and daughter understood that the father got isekai-ed immediately. I wish more media (game, tv, movie, books) etc have characters who actually are aware of tropes. The one that annoys me most are zombie movies. Somehow, the stories are always set in universes where zombies are unheard of.
