Maybe, but Trek was a reboot, not really a sequel. it took a franchise with a huge and loyal following, but was so tightly restricted by itself, not much more could be done with it, and opened it back up. I don't see Ice Age and Madagascar having the same following and fan quality as Star Trek.
From the perspective of people who don't want to watch Trek it probably doesn't matter whether its a reboot or sequel, just as how no matter what they do with whatever franchises you and I may not like, it's still not something we're going to care for or want to watch.
And "fan quality" isn't what really drives the industry since Hollywood is a business, and if a crappy movie can sell $900 million in tickets, they'll make decision accordingly. Trek has great fans, but Trek XI did not succeed because of Trek fans. It was a success because of the general movie audience (the same who make stuff like Ice Age and every other big movie a success) who were attracted by the film for whatever reasons.
