Braga's non-involvement with Nemesis
notwithstanding, that film was not "pure," unless you mean Pure Grade-A Disappointment.
They had four years since Insurrection
to craft something truly special and worthy of the TNG cast. This was their last official on-screen adventure, and that was the best Berman and his people could do?
I'm as fond of the Prime timeline and the Roddenberry and Berman eras as anyone here but that last film was a mess, a mess that helped tank the film franchise for close to a decade.
