Until fairly recently I would have gone along with the Black Hole/New Beast idea as well. I used to really like both of them back in the early '90s, Beast especially because of the whole "Holy **** there's no seatbelt!" aspect.
However, I've ridden similar models since, and they are in fact pretty crap. That doesn't alter the fact that I used to love them. It just means that I don't "miss" them, as if they were still around I'd probably detest them by now. I've got great memories of them, and I'm actually glad they're gone so that doesn't change.
I have similar feelings towards Rhyl Ocean Beach. I've got fantastic childhood memories of it, but it was actually a serious dump, at least towards the end of its life, so I don't in any way miss it. I'd rather have the pleasant memories I have than have them obliterated by that place somehow managing to cling on even longer.
To answer the question, I'm not sure really. I LOVED Magnum Force, but completely agree with Flamingoland's decision to get rid of it, even if I would love to ride it again.
