I read the comments and mostly they seem to agree with the 'little robotic' eyes Skivee cites. I do not agree. Obviously, yes, they have been trained/taught the delivery desired; on the other hand I have seen many a group in the US with less affect. It seems to me that many performers concentrate so fiercely on the performance that they have little to no time to devote to the niceties such as engagement with the audience or each other.

For that matter, many an audience appears robotic.

The kids are very good.
