I couldn't take her seriously in EE as a 'club owner' and the notion of her as a PC is frankly laughable.
Although the height restriction has been abandoned by the Police Service, they still require officers to be of a reasonable statture with weight being proprtional to height.
In the case of this actress, who appears almost cuboid in a uniform, the notion of sufficient gravitas to comand respect among the public she serves is obviously absent. Add to that her voice and manerisms which make her appear to about twelve, and you have to wonder if she would ever get through a basic selection process.
Since it is a drama, let's just confine ourselves to the simple fact that she is a lousy actress, and there are thousands more suitable actressess out there who could pay the role far better.
