Other than the "milan" pronunciation issue that others have outlined: the same word is pronounced in exactly the same way every time, which sounds wrong especially in long words such as "availability". The speed is too uniform; Polly handles commas (and full stops) brilliantly but there are other occasions in which a huan speaker pauses ever so slightly, for example to take a breath. Humans don't pronounce every single word fully, which contribute to make speech sounds fluid, this seems to be lacking completely from Polly.
