I liked Wesley in "A Quality of Mercy" but hot damn, he nailed it here. He is easy to recognize as Kirk and yet is borrowing very little from Shatner's performance. Wesley has managed to "echo" Kirk in a way that Peck and Gooding haven't quite dialed in yet for their characters.
It's funny—given that in both appearances he has depicted an "alternate" Kirk, he's had some built-in leeway to miss the mark and still be credible. He doesn't need it. This man can play Kirk.
