While I thought Pine did a fantastic job (particularly in the first movie) he is no Shatner. Shatner as Kirk is what makes Star Trek for me.
Which is why Pine would have done just fine playing a new character instead of trying to retread everything.
There are scads more interesting universes that are plausible, from book authors.
Star Trek 2009 was every modern geek's fantasy: Rebel Without a Cause, cum 22nd century - each character has attitude - hot green chick, with Lara Croft elements - Vulcan is not a Utopia/Spock is the primal geek so he must be bullied - hotrod looking Enterprise......what else?.......
What Howard said about Hollywood could be so. Certainly regarding Jackman, who likes substantive characters. I think Downey is fine with Iron Man (though his Sherlock Holmes was a lot better, more interesting character; those stories are good, too). I think Hemsworth has enjoyed Thor's growth out of innocence. He's the most interesting character in the MCU. I think Chris Evans wants more of that kind of thing in his character, and in the MCU. The MCU could and should be written more like the 60s/70s comics.
On a different note, I wouldn't be surprised if Evans is getting a little worn out. He got big for Captain America, and like Hemsworth and Henry Cavill has gradually gone down in mass. He has no chest, and they've padded his suit the last two or three movies.
