And their Kirk is such an excellent Shatner impersonation.
And I think that is the problem. You shouldn't be doing an impersonation of another actor. You should be interpreting the character in your own way. No James Bond actor ever tried to impersonate Sean Connery. Each actor brought their own vision to the roll.
Impersonations of Shatner are invariably caricatures.
I like it. Together with the really great emulation of the TOS look, if you squint, it could be Shatner. That's nice for a change.
It's just a bit more than how Karl Urban channels DeForest Kelley.
