Besides any future films rely on HSM4 actually being well received. It'll probably get an instant rantings spike, but its the numbers the subsequent repeats get that will determine if it goes any further.
I don't see myself watching HSM4, Ashley, Zac and Vanessa made HSM for me, It wouldn't be the same really without them.
I'd rather there not be a HSM4, if the orignal cast isn't there.
The premise of it is good..and it would be a brilliant storyline if the original cast were to come back, but would it work with a whole new cast? Ehh, maybe not..it all depenRAB on the way the characters are introduced to us really.
Do they have to make another of these dreadful films? Although, I notice that its back to a TV premiere. Didn't the last one do very well at the box office? If it didn't, then part of my faith in human nature is restored.
