I concur mostly with what you've said; she's far from the most passionate lady I've seen and her OWO is, quite frankly, crap but I did find her very beautiful and enjoyed my time with her despite not really feeling the chemistry I've had with a few other girls.
I feel like she has a lot of potential to really become a HOD star if she injects a bit more passion and practises her oral technique but you can't force this kind of thing and I'd rather she be genuine than put on an act.
