There’s a lot of good in this film, it’s just unfortunate that it didn’t get the polish it deserved. I don’t think it’s a train wreck like most people think.
Nemesis honestly had potential going for it - Picard going against a younger clone of himself, Reman slave uprising overthrowing the Romulan Senate, find an early prototype of Data right before his death is legit great concepts.
The problem was that the film was directed by a film editor, which is nothing wrong with that, but Stuart Braid had zero lore knowledge about Star Trek and he refused to have any help ironing the problems and a extremely gawky screenplay that had a weird fixation with Wrath of Khan. And even if Nemesis was a better film if executed better, Paramount made the retarded decision to release the film in December when the second Harry Potter and Lord of the Rings movies were dominating the box office at the time.
