No I think it will ruin it :(
And they aren't even using the new characters (Rocketman etc), what was the point in even introducing them you know?

Yes it will ruin it it won't be the same as 1,2 and 3 they need to be in hsm 4 to make better it won't be the same without zac efronand vanessa hugdens

HSM 4 I don't know because they go to the university but University Musical will be nice :)

no because all the normal actors were just fine for this movie and zac effron isnt in this because he said he wont do anymore disney channle movies

I think that it will just be bad. I really like all the HSM's but another one might be too much. I mean, it has been great watching all of them, but I think they should change the story line. It does get a little boring once you think about it.

no

it might be nice, i mean disney makes great movies. removing the original cast'll just make it kinda weird.

Either have the original cast, or risk losing heaps of fans.
