Nope. They are PCS over-rated Evgenia and Alina, one-two punch of Eteri's Russian ladies hype machine.
There's no similarity whatsoever. A different era, very different competitors too. Plus Alina and Janny have the same coach, and both are very young. This is Alina's first year in seniors; it was Tara's second and she was the defending World champion heading into the Olympics. Janny has been a fairly consistent rotator, but her PCS are overdone. The entire field today is an entirely different animal. There's a lot more depth in many countries. This is Alina's first year in seniors, and her PCS are over-rated as well. Next we have the huge factor of the one-two punch Canadians, which did not exist back in 1998.
The comparison with 1998 is a huge reach. Janny (being injured and therefore not competing) did not have perfect performances at Russian nationals the way MK did in Philadelphia, which is more memorable than Nagano in the first place. The comparison sounds like an Olympic-frenzy talking point to ramp up interest in what seems more like a foregone conclusion. I certainly wouldn't see Alina winning gold as any kind of upset. The upset would be if Kaetlyn Osmond got her act together and landed on top of the podium, and if Mirai triple-axeled her way to at least bronze.

Say what? I don't see how you arrive at those conclusions. Evgenia is more like Tara -- talented technically, but way over-studied presentation-wise, albeit graceful. Neither Evgenia now, nor Tara in her heyday are anywhere near Michelle Kwan interpretively and artistically. Carolina Kostner has come a very long way. At her best, Carolina does come close to Michelle in some respects artistically, but not technically. Carolina beats both Alina and Evgenia by way more than a mile artistically!
