K, I just did a HUUUGE long review on my recent viewing of SA on another site, but I'll just basically give my 2 cents on Kyle for now:
He's a VERY very talented guy, there's definitely no denying that. But seeing him also made me realize just how beautifully nuanced Groff's performance had been. Kyle is very good at doing the edgier, more "rebel" side of Melchior. It's only in the "sweeter" moments where he fell flat for me. The problem is that... it was those very moments that made Groff so likeable. When you only have the hard-edged, almost-pretentious Melchior, you don't really feel as much for him in the end.
That said, considering I think this is his first venture into the acting world (I could be wrong on that), he definitely was not BAD! He just...wasn't as effective as Groff in my opinion. That's all :) (by "effective" I obviously mean he didn't make you feel for him as much)
Vocally, he was definitely spot on. He has a great voice. I don't personally find it quite as BEAUTIFUL and easy to listen to as Groff's (his falsetto is strong but just naturally a little bit nasaly for my taste), but def really good!
In short... I miss Groff


(no seriously, I always knew he was awesome, but seeing another take on the role completely accentuated the fact that Groff nailed that performance. Could his Those You've Known sometimes be a bit overdone? Absolutely. But all in all he made you love him, and...I think people probably took his ability to do that for granted a bit)
I don't need a life that's normal. That's way too far away. But something next to normal would be okay. Something next to normal is what I'd like to try. Close enough to normal to get by.
