So we have a mystery episode. That sounds like it be pretty fun. This episode is fun, but it's greatly lacking in substance. Let's start with what I like. Well, Barbie's sisters are all in top form. The new schtick with Chelsea trying to be like Sally Snoops is pretty fun and shows how intuitive and imaginative she can be. It's fun to see her basically lead the case. The one shot characters are fun, particularly Vanessa. The ending with Gato the dog is pretty sweet. The message on bit jumping to conclusions is fine. What makes this episode flawed? Well, it's the Barbies themselves. They act interchangeable and you don't really get a good grasp of their characters. It's just one of them says something weird and the other says something weird, and doesn't play into their individual character strengths. There could've been something great if the episode just did the whole "good cop tough cop" routine for the whole episode and not just one scene that's played for a joke. Also, again with the Otto Phoenix stuff? Actually make us care about impressing him and don't just use him as a bland plot device. Look at "Barbie, Brownies, And Bears Oh My" from Barbie Dreamhouse Adventures. Barbie was actually smart and took the time to question her family on who ate the brownies, unlike here, where she jumps to conclusions over everything. Brooklyn Barbie is just there, no wit or real intuition. This is wasted potential.
