Considering the little amount of time to practice and the fact that they had to get so many girls up to a level that they could perform on a stage, this is pretty good! They're idols, I don't think too many idol fans are looking strictly for talent from the industry (or they'd be extremely disappointed and probably give up on it), so the content of this endeavour is fun and interesting and cool and, for what it is, well-done.
For instance, many people on this board like Buono!, and we're all aware that the girls aren't really
rocker chicks. It's about image, and when they screwed around with instruments on stage it just showcased the usual attitude of H!P's "Look at us, we're so debutante and that's what makes us adorable!" When AKB pulled off actually
using instruments in that performance, it's cool because it's a novelty that, for this industry, was pulled off well. I don't expect them doing something like this for their next single, so it probably is
just a novelty. Since the music and images are created by the producers, anyway, unless you're these three
, talent isn't a huge deal in today's idol industry. Just a bonus.
How unfortunate this is is subjective.
