As Riley turns 13 and goes to Secondary School she is taken over by Anxiety, along with Envy, Embarrassment and Ennui. These teenage emotions remove her from her happy self-confident self and make her desperate to make friends, at the expense of being nice. You can guess how it ends.
There are some good moments. Ennui is never bothered by anything, except when she loses her phone. I liked it when she introduced sarcasm too. But there's rather too much ice hockey and the extra bits about the brain don't add much.
Alex rated it as two fingers pointing at each other (middle-middle) and I'd agree.
