I'd say generally not. Disney has a good habit of churning out good quality films while also being able to experiment some – yes tomorrowland flopped, but what was the last one before it? The key to the Marvel franchise is how Disney will re-incorporate it to parks, merchandise, and everything else.
Thanks for sharing that article. It is an interesting premise, but the writer doesn't cover all of the bases. Fantastic Four didn't flop because of superhero fatigue. It flopped because it was a bad movie. The article references Thor: The Dark World, which had the weakest story of any Disney-produced Marvel Film, and it didn't do as well. Disney knows that audiences are drawn to great stories. This is how Marvel made Ant-Man such a success. I wrote on my website:
Ant-Man stands in stark contrast to Avengers: Age of Ultron, the special effects bonanza from earlier this year. In fact, it is different from most of the Marvel films that came before it. Ant-Man shrinks to another level to give us the details of the characters to help the audience understand their motivations. It makes us care about the characters — even the ants — by forcing us to have a deep relationship with them. http://www.thedisneymoviereview.com/marvels-ant-man-is-a-refreshing-look-at-superhero-movies/
Age of Ultron and Ant-Man succeeded in different ways, but it was all based on story. The one thing that I think is odd about Fantastic Four is that most audience-goers seem to know that Disney's Marvel did not make this film. It's odd because Disney does not receive this same leeway with WB's Pan. Anyway, I could talk about Disney Movies all day--as you can see--but you can read more about Disney movie news on my website, http://www.thedisneymoviereview.com/.
Yeah I mean you have think there were plenty of factors why "Fantastic Four" tanked:
1) The terribleness of the previous Fantastic 4 movies.
2) The fact that it was a reboot which focused mainly on rehashing that origin story yet again.
3) The relatively unknown cast.
4) The history of FOX making crappy superhero movies (other than the main X-Men franchise.)
5) The terrible trailers which got almost no one excited for the movie.
6) The many leaked plot decisions that sounded stupid (like most of the Dr. Doom related stuff that leaked.)
7) The terrible handling of the Johnny/Sue relationship reveal. The moment that they cast an black Johnny/white Sue there was controversy. The correct thing to do was to come right out and clarify the exact status of how they were related immediately. Instead they chose a combination of ignoring it and being mysterious letting people speculate and argue practically constantly right up until the release. Which built up a even more negative emotions towards the movie as people got sick of hearing about it.
8) The reviews...not just from critics but from people. And it wasn't just that they were critical of the movie based on pure opinions on things like acting and such, but it was facts like there being only 10 minutes of rushed actual Superhero action at the end of the movie which felt disjointed from the rest of the film. Which sounds an awful lot like that first terrible Fantastic Four movie...
