I can agree with multiple films, but if controlled, like a duology or trilogy, it preserves the specialness and makes you know and plan ahead what to do. Like look at Nightmare on Elm Street; out of the seven films, three of them are good: 1, 3, and 7. If the Freddy series was a trilogy of those films, we wouldn't get 2, 4-6, especially 6, for good reasons.
So if they decided to do 2 or 3 films here, I think it would've been a better idea.
And look, I tried, several times, to watch HIII, but no luck. Its not a good movie. Not against the anthology idea, yet if that went forward with III, or even II, we wouldn't have gotten what we did get for better or worse with these films.
And again, really would like to have seen the 2012 reboot that doesn't remake, or directly continues after the original 1-2, but restarts like an actual reboot.
