I think some folks have ignored the fact that Section-31 pretty much ran afoul of the TMP condition.
It started out as a multi-episode series and got forced into a 90 minute movie.
We were lucky with The Motion Picture in that it had been a decade of only reruns beforehand and the fans were hungry for more new Trek adventures.
It was received at the time, mostly with applause from the fandom and did well enough to get Paramount to continue making movies.
Section-31 came at a time when a lot of fandom was Hellbent on wanting things to line up with their own particular headcanon.
(it doesn't excuse the clunkiness of the movie, but it does explain much of the fandom reaction)
Yes most Trek fans including myself don't care for the Section 31 streaming film.If Hollywood was so cutthroat to kill a career after a single failure, we'd have never heard of folks like Alfred Hitchcock or Steven Spielberg beyond a footnote in a book about cinema history.
That said, realize that the film itself got good minutes viewed and brought people to Paramount Plus.
The film gets good enough ratings that they still occasionally show it on the Showtime subscrition movie channel.
Just saying.
