The only kind of reboot I would have no interest in would be a remake like Gus Van Sant's Psycho, which was a close duplicate of the Hitchcock film (almost same script, almost same score, and some scenes were even shot-for-shot reproductions of Hitchcock's edit).
'Soft reboot' strikes me as something not too far from 'sequel' - which I'm not averse to - but with all-new characters (and same story-verse, no retcons). I think the term 'sidequel' is more self-descriptive. If we were talking about a TV show we'd simply call it a 'spinoff'. IOW it's really not that big a step from what's come before.
A hard reboot, OTOH, simply needs to treat me with some new interpretation of the material, either in theme (like Ronald D Moore's Battlestar Galactica), or visualisation (like Christopher Nolan's Batman), or preferably both. After all, I'm very much looking forward to Villeneuve's Dune, despite the fact that this will be the fourth time I will have had the same storyline, same characters, and same setting presented to me. I have faith that Villeneuve will show me something worthy in his interpretation.
