It's interesting that even in the years after Jurassic Park III, when Jurassic Park 4 failed to materialise, no Hollywood studio tried to make a dinosaur movie. The closest thing we got was King Kong, and that doesn't count because the dinosaurs weren't the focus of the movie and just happened to be there. I wonder if studios saw the downward trend in box office returns for the Jurassic Park trilogy and figured that franchise (dinosaur) fatigue was setting in.

It's annoying to see because it's such a simple thing. I've noticed it as well - people type 'women' when they clearly meant 'woman,' and vice versa. Oddly, this doesn't seem to happen very often for man/men.

Stargate simply isn't that big. Its fan base has always been modest compared to other sci-fi/fantasy franchises, meaning that the expected audience for a new show isn't that big, especially since what fans seem to want is a continuation of the previous franchise that respects all that backstory and lore and might not be welcoming to newcomers as a result. Combine that small audience with the expense of making sci-fi TV that looks good, and the business case for a new Stargate show isn't as strong as some fans seem to think.

MGM had years to bring back the TV franchise after Universe was cancelled, but they didn't. They have The Handmaid's Tale and are involved with Vikings, so it's not as if they're not interested in genre TV.
