BBM review astroturfing on Google Play?

I just got my invite to BBM and thought I'd install but the reviews seem eerily familiar for the app on Google Play:

Review, after review in the same manner...

Okay, they might be genuinely commenting on how it is "user friendly and smooth" but I'm put off a little by their familiarity. I've had a look on my iPhone and the reviews have a distinct lack of any mention of "user friendly and smooth"

What do you think? Shenanigans or unfortunately similar reviews?
