He's right about the way "Spock" is written in Generations. Scotty and Chekov get some truly awful dialogue; Scotty especially is teching the tech in true late-TNG fashion. It's painful to watch. Imagine if they'd make Nimoy say that crap?
"Brought a tear to my eye," was obviously a line meant for McCoy. They just swapped him for Scotty. Paint-by-numbers scriptwriting.
The TNG 24th Century technobabble dialog the writers gave Scotty to say took away the illusion of this being the same crew we just watched in the last six films.
Why everyone thought the first TNG film had to be a mixture of both crews has always escaped me. They ended up doing a terrible disservice to both crews.
