Here to address one comment I see often... "IAM = boring, all the same choreos,,, etc more teams should go elsewhere etc"
Here is my take on this... I watched the top 8 again... 4 teams come from IAM 4 teams elsewhere.
My favourite compositions for the rhythm dance are probably PC HD FBS and SB. 3 teams from IAM
My least favourite compositions are CB (they have an amazing FD though) Piper and Paul (I like their Elton John but I feel that another vehicle may have helped them remain closer to the podium, especially at the Olympics, with such a panel) SK (no matter how well they skate, they have my least favourite two dances combo from any teams in the top 10) and GF (there is nothing Michael Jackson like in this program.. they skate it super well but it's not street dance)
So only 1 IAM team from the top 8 has a not successful RD, while 3 are not great IMHO. We could extend this to the top 10, with two more teams from IAM or if you prefer top 13 with another 3 teams from IAM,
In many years of ice dance watching, though I dislike the theme and pattern chosen this year with great passion, it has been a very diverse and entertaining event. I think IAM deserves more credit to what they do for the sport.
Will it be even better with other schools getting open elsewhere : yes. But let's give credit where it's due. Marie-France, Patrice and Romain are killing it, and it's normal that there is a IAM style to it... there is nothing wrong with that. In the 90s, there was a clear Russian balletic/dramatic style to ice dance. It was very beautiful to watch. It was however even more homogeneous than IAM... I would like to see more "ballroom/latin" intensity (not possible in this RD) because I personally find the "sportive" qualities easier to note, with the high intensity of a jive, quickstep or a samba etc.. (and I guess that's why I love the parrots) but IAM is doing very well.
End of long post

YMMV
