I think I can partially forgive Lucas for some of his gaffs in the PT because he gave us the OT. But I cannot forgive Abrams for what he did to Star Trek and so the flaws of TFA are far more glaring to me and highly annoy me to a greater extent.
In my opinion, Star Trek’s Prime Universe had long since cornered the fan base. There are people who like TOS and its movies but don’t care for anything else; people who hate DS9 because it’s not enough like TNG; people who hate VOY because it’s too much like TNG; and people who hate ENT because it’s generally unoriginal. And/or they hate (pick anything post-TNG) because damn you Rick Berman.
So the Trek franchise needs new fans. Enter JJ Abrams, who says he injected some feeling of Star Wars into Star Trek. Great. Sure. Fantastic.
But the Kelvin Timeline (aka JJverse) events don’t overwrite the Prime Universe. In Star Trek, anything that can happen does happen in alternate quantum realities. Therefore, both universes exist, and JJ didn’t ruin it.

JEDIT: You just wait until Star Trek: Discovery comes out. Fans are going to come out in droves saying it sucks because reasons.
