I also find Karamysheva underwhelming. She's beautiful but I think it's just an unfortunate side effect of the documentary/social media hype since she was a first-year, you sometimes end up expecting too much. Recently I liked her a lot at Moscow IBC, but ultimately agreed with her placement behind all her classmates plus the 1 junior, Sultangareeva. And when she started getting solo roles at the Mariinsky, I felt like I understood why she wasn't given any solo parts at the graduation performance. Maybe it was just nerves but I just couldn't see any soloist qualities in her, which I understand she isn't a soloist but you'd think she would need some level of that to receive a solo role. Some of her performances have seemed as premature as some of Koshkareva's, imo. She looks very sweet onstage but I cannot comprehend why she is receiving solo roles over dancers like Savelieva who are stuck in the corps. Even Ionova doesn't seem to be up to much nowadays.
I would love to be proven wrong by Karamysheva though, she does seem sweet with a very cheerful presence onstage, and I have nothing against her, I just always find it surprising the way people see her on this site.
I haven't closely watched her performances, but from what I've seen, they appeared technically clean, nor did the roles compare in difficulty to what Koshkaryeva danced. But if management thinks she's capable of dancing Prince's Friends of the Bridesmaid variation, I'm here for it. Also, what we see in tiny IG or YouTube videos is a weak facsimile to to what the audience experiences. Some dancers step on stage and their charisma is palpable, so I try to reserve judgement unless someone turns in a noticeably weak, underwhelming performance — and Koshkaryeva's straight out of the gate soloist roles were subpar by any measure — and I just haven't seen that with this young dancer. I'd give her time since she's still adjusting to theater life.
