I’d base the TV show results on the simple observation that the shows aren’t really being discussed beyond comic fans. They’re like most other comic TV shows, maybe less popular than Gotham, Arrow, Flash and Supergirl. They’re ok TV, but not getting anyone really mainstream interested.
As for the movies, the X Men have always underperformed, but in this comics golden age they’re just not seeing a good return. They can barely break 600 million in an age where 800 million is standard. Marvels most popular character (Wolverine)should be a Batman or Spider-Man type franchise but instead he’s a small return character. Except for Deadpool the X franchise is a whole bunch of meh results. Not FF bad, but not that far off. They’re run through all the best characters, all the best storylines, all the best actors and now there’s not much left to use.
So yeah, on a purely numeric basis the well looks shallow and on a franchise building basis they killed all they best characters and have a cast in place that people couldn’t identify if they wore “I’m an Xman” t-shirts.
