Arts good. But Mandy's showing too many emotions. She's at her best when she's either showing cold indifference or tranquil rage and I'm not seeing much of either here.
while yes i understand where you guys are coming from and due to the show only ever depicting her as such it makes sense to assume that Mandy would just be exactly the same as she was the majority of the time in the show. but, it is important to note that we never see a proper future version of Mandy as most iterations are either A: version thoroughly corrupted by demonic power that she acquired at a young age thus remove an real chance of emotional development as she has become a dark overlord that only seeks to crush others underfoot or B: a hyper stylized version as seen through the imperfect idealized lens of someone (including herself) that is and does whatever the beholder thought she should be or do. this leaves us with the very real possibility that simply through puberty she would show the wide range of emotions she is known to have but refuses/ is unable to show which would have been entertaining in its own way provided the writing was solid
