I suppose I should start talking about it a bit as someone who didn't own a Nintendo switch.
Calyrex is the worst Pokemon yet, with its combined forms (if you can call it that) was just as underwhelming. I think the biggest problem in regards to Calyrex was that its proportion is so awful that it's actually distracting. I think it would be much better if they go for a knight theme instead.
The legendary horses were pretty uninspired. Their designs don't spark much personality, and at best, they look like regular Pokemon more than anything.
On the other hand, I do like Galarian Legendary Bird Trio, especially Zapdos. But that's it. I don't hate Galarian Slowking, but I have nothing else to say either.
lol Tapu Bulu gets outclassed by a regular starter is hilarious to me
