The tension dissipates. And the final pay-off, which is effectively Wedler trussed up in the world's worst mermaid costume, is a borderline insult.

It is flawed, but has a good performance by Wedler.

Rather like its misleadingly punny title, "Blue My Mind" wants to work on multiple levels, but falters to become a slightly unconvincing, if well-made, single-entendre.

Thirteen meets Ginger Snaps in this Swiss queer coming of age film that reinforces the intimacy of teen girl friendships and the horrors of our changing bodies. Features gorgeous cinematography and a fantastic lead performance by Luna Wedler
