As Unicorns are my favorite mythical creature, the title drew me in right off the bat and got me to read the synopsis. The story follows a young girl named Davina, who begins a relationship with an older guy named Sterling. Things end up getting ugly as Davina, who is prone to escaping into a fantasy world, finds that Sterling isn't all that he appeared to be.
Overall, I thought the acting was good, and the interactions between the leads were great. They were very fun and playful, and seemed to be a good match on the surface. However, there were some scenes between them that were uncomfortable to watch.
As for the production, I thought it was almost trying too hard in some respects to be "artistic", leaving me scratching my head (and I absolutely adore the Moffat era of Doctor Who, so it takes a lot to do that). The visual effects were outstanding, though.
