It's OK but the concept is more like a short story that's been stretched into a full length film. I don't recall much in the way of lines being spoken so it must have been pretty easy to rehearse!!! CGI is OK and believable enough. To be honest I wouldn't bother if someone asked if they should watch it. I think the narrative is a little lacking - I would have added her back story flashbacks earlier to understand a bit more why everyone hates her so much. It added nothing keeping that to later in the film. Also did her mum die and then she took over the house? How did she make her money? What's with all the letters she writes to her friend. Etc etc. Is that therapy? Why not explain that a little. What are the dresses for?
Lead actress did a good job. Needs next film to be better quality for her career!
