Found a stream of the documentary that aired about Johnny's Junior. If anything I wish it was longer as I am sure there was plenty more to be seen. That said I was happy to see what they showed.
For those wondering which Juniors are seen it is pretty much just the Tokyo Juniors even though they show a bit from Sexy Zone's Osaka SUMMARY concerts. And the Juniors they focus on are the ones that are mostly the regulars on Johnny's Jr. Land. There are a few exceptions for this, like Takada Sho and Yasui Kentaro get some screen time but it is mainly that group.
Iwahashi Genki gets a good deal of focus, from his studying for school and nerves for performing in the concerts. Haniuda Amu also gets a good amount of screen time, partly because he messed up for one of the performances. Chino Aoi is boss in this, as apparently the older Juniors that joined after him do call him Chino-senpai. That and for his age he really seems serious about his work. These three are the ones that left the biggest impression on me and I will be keeping my eye on Genki as he impressed me. And I would not be surprised to see Chino get to the the Golden Junior in the near future as he seems to be as much a little star in the making as Morimoto Shintaro was, IMHO.
If you just want to watch for the Bakaleya6 then you need to skip to the second part. They have about 8-9 minutes dedicated to them, from some of the drama filming to their SUMMARY concerts. Otherwise the most you see them is for the Shiritsu Bakaleya Koukou movie commercial that looks like it was played at each commercial break. Though it is not so bad seeing that Uchi Hiroki and Question? are not seen at all (minus Bakaleya footage for Uchi) even though they also had SUMMARY concerts.
Also they had the first Golden Junior included as Takizawa Hideaki talked about his time as a Junior. They also had some footage of a couple of the big name Johnny's when they were Juniors, like Yamashita Tomohisa, Yamada Ryosuke and Imai Tsubasa. And I have to say I really see what people were saying about Sato Shori looking a lot like Imai Tsubasa when he was younger. The two look like they could have been brothers going off the old Tsubasa footage. So as long as Shori does not gain the penchant for growing facial hair like Tsubasa does he will definitely be growing into a handsome man.
If I find something better than a stream I will do a review of the documentary. Honestly I am hoping that they will release this on DVD and/or BD. I would buy a copy in a heart beat.
