Depends on if the movies are any good.

Planet of the Apes is very popular. I think the 2001 reboot failed to produce a sequel despite its massive gross because it was shit and no one wanted it. Now, I and probably many others want to see Dawn of the Apes.

Alice in Wonderland 2 is going to flop. It's too long since, it doesn't even need a sequel, and itself was completely indistinguishable and generic. If any studio is going to kill this revisionism, it's Disney. Half-hearted awful product that wastes film and/or time.

But is it any wonder, when the big titans of the last decade have all pretty much wound to a close...yet Spider Man's already been rebooted, but looks to peter out again this year. IMO the era of those titles is up from Pirates, to Batman, to LOTR.

I'm gonna go with never. You know WB is counting down the days until they do Harry Potter again. I think the next big trend is to remake movies that originally did poorly at the box office or critically.

There are lots of failed attempts as well though bigger/known property movies are still big and mid-tier movies are bleeding at BO. Till you give the audience an appealing product I believe they will still show up. I mean Godzilla is a known property and has had a lot of foreign movies but this one will open on its own merits. If you give the reboot of Godzilla every 3rd year I think that's not going to work but if time enough has passed I am sure new generation would like to see newer version of classics or movies they think would look good with new technology.
