X-Men is actually the 1st movie based on Marvel Comics that did really well, the first movie that earned more than $100 million at the domestic box-office. With Marvel Studios, they had a lot of superhero films to look at, like they already know which films worked and which films didn't work, releasing superhero films is not rare anymore. FOX didn't have that back in the late 90s when they were developing the first X-Men movie.
Yes, X3 could have been massive. The opening weekend was astonishing. But, thanks to the outcry from fans and the mediocre reviews, it lost its legs. If it had been a better movie, it would have had great legs.
