Just saw the "Tenka wo Toruze!!" DVD and it's definitely worth checking out. I almost skipped it because I thought it would be more or less the same as the other SKE DVDs. It's true to some extent, but it's has much more old school unit songs and a lot more KII!
It's pretty interesting. Some of the KII girls are naturals and some other definitely need some work. Overall they're looking good. It's great to see them having fun on stage. Some of them have horrendous vocals, while others have a very sweet timbre
Rena is radiant as always, yuimin is hot as always and there's seems to be a bit more Rina as well
The Wimbledon performance was pretty sloppy... nothing unlike the one on the S2 DVD. The Skirt Hirari has an excellent mix of Team S and Team KII
So yeah, definitely check it out this DVD!
If you're interested in buying an SKE48, I'd recommend the S2 DVD: very well made all around and a cheaper than the 'Tenka' DVD.
