Oh, God, yes. I still remember the Great Reboot Wars of 2009. I got no actual writing done the weekend the first Abrams movie opened because I kept getting caught up in heated arguments with fans who were practically livid about the movie. And, yes, some people got
very emotional about it. Judging by some of the posts, you'd think that Abrams had personally spit on Roddenberry's grave while slapping every fan in the face at the same time.
(I remember, in particular, one poignant--if hopelessly misguided--post from a young teenage fan who genuinely seemed to feel hurt and betrayed by the movie.)
And, to this day, you still see people describing the Kelvin movies as "Not Real Trek!" or an "abomination" or a travesty or whatever.
And as for
Enterprise . . . how dare they cast the Vulcans in such a negative light? It's character assassination, it's "violating canon," etc.
We've been through this all before.
