I'm still confused how Denise Crosby would've made Nemesis better except for the hardest of hard core Trekkies?
I think you nailed it right there
But if they wrote a decent script using her character...who knows?
, in my mind, that would've been a good enough reason to do it!
Part of the issue with Nemesis was that the general public didn't like it and
many fans found it insulting. Having a Sela cameo in the opening scene in the Senate wouldn't have helped at the box office, but it would've been the smallest of gestures to acknowledge the decades-spanning franchise behind the film, and not left such a bad taste in many fans' mouths.
