The market seems to have changed significantly in the past few years, however, as franchises are increasingly favouring continuations over reboots. Having continuity that's "too complicated" and "not accessible" didn't stop Heroes or The X-Files from coming back as continuations in their original continuity, for instance.
I've started to think that this is because TPTB are discovering that reboots use up a lot of creative energy that isn't necessary (from a business perspective) in order for the franchise to work (i.e. make money). I mean, what's the best-case scenario for a reboot? Audiences like it enough that they want...a continuation. The worst-case scenario is that you get something like Jem and the Holograms--a product that misses what was appealing about the original in the first place.
I saw the comic of jem recently. I was horrified.
