Why Platinum Era is awesome

Morning Musume has different eras. First we have the Golden Era (which was like 2001-2007 I guess? idek) and the Colorful Era (2011-Present) Golden Era I guess ended when Yossie graduated and the Colorful Era started when the 9th gen kicked in. But in between the Golden and Colorful Era are one of the best lineups It was the era where Aichan was leader, consisting of 2 5th gens, 3 6th gen members 1 7th gen member and 3 8th gen members. Yes, you got it right its the Platinum Era. From Onna Ni  Sachi Are to Onna To Otoko No Lulluby Game was the Platinum Era member line up. The thing I like about the Platinum Era lineup is there are no 14-15 year olds (there youngest was Mitsui Aika who was like 17 years old) So most of their music videos are more mature and awesome. Even their singing voices are better than the current lineup (if now we hear 90% Riho and Sakura during that time it was Ai and Reina) but I have like the current member line up (no hate at all) after Koharu's graduation in 2009 the member line up was still Platinum Era but not 100% but when Eri, Junjun and Linlin graduated That was the end of the Platinum Era. Well tbh (to be honest) their dancing wasn't as nice as the ones like in Brainstorming and Ai No Gundan. They were just like Physical Education routines. I read an article that the Platinum Era choreographer moved to akb48 in 2011 (end of Platinum Era) so I see why akb's dancing isn't really nice. For me the Platinum Era really ended after Takahashi Ai graduated. Even if Sayu is the only one remaining in the Platinum Era and that really hurts. Please continue supporting Morning Musume :D
