While it's hardly flawless (indeed, I think every Trek film has notable flaws): TWoK.Let's settle this.
Fans, what is the best Trek film? I'm sure if we have consensus on this consensus on what makes a Trek show great will be easy.
I'll start: for me, it's a tie between 09 and TUC.
But I assume you're being sardonic and the whole point of asking the question is to establish that there is no real consensus (though I think TWoK might broadly have consensus).
Notably, TWoK not only has shoot-'em-up action to spare, but also includes deeper messages about aging and regrets.
