Rani still facing an inferiority complex due to feeling like a Maria replacement could feel like retreading old ground but it actually works here in a way that similar themes felt drawn out with Martha / Rose. The fact that the character in question is a child and has had plenty of character moments of their own helps sell it. K-9 is back - which is a major boon. But that’s about it for the positives. This story had too many false endings and muddled character motivations. Too many things happened “just because”.
