I'm familiar with 'the qualities most film buffs feel good films should possess'. None of the eleven movies released under the 'Star Trek' banner possesses very many of those qualities. If most people are prepared to say TWOK is the best - TVH is my favourite, but whatever - they needn't be thinking TWOK is anything other than a successful popcorn movie. Which there is nothing wrong with it being.
There's no point judging ST09 by the standards of the TV shows. You can only judge it by the other movies. And I think it holds up very well, to say the least.
