For the OG's. Maddie and Chloe were both super talented for their ages when the show started. Paige was talented but not as much as M&C, Kendall was fairly equal in talent to Paige. Makenzie was super young but a great tumbler at her age (she was too young to do much dancing). Brooke was older and not special for her age, Nia was pretty average for a comp dancer and Vivi was good for her age (but not as good as Makenzie). Vivi is the only one (besides Maddie) who is still dancing.
The problem with this new group is they are just too old. It's not that impressive to see a strong dancer in the teen division as it is when they're dancing as minis. However, the only reason the OG's were able to do those first two seasons is that they were performing dances they'd learned the previous year/summer. Dancers that age just can't learn and retain choreography as fast as is needed for a show a week.
I heard from some moms who were at the taping for this weeks show and they said the entire audience was confused by the routine. It apparently was danced to Shout and they changed the music. Apparently, they were also passing out missing posters for the dancer that didn't show this week. I guess they dropped that plotline.
The Yolanda and Stacy plotline is just so over the top and fake because there is a lot of photographic proof that Lilly and Elliana were hanging out a lot while Abby was in prison. Doing Jordan Matter photoshoots and stuff. If they could hang out enough to do a Jordan Matter shoot then they're not mortal enemies who can't be seen together.
