Have none of you seen Mary Poppins?
Annie?
Amadeus?

You all have the nerve to even categorize 'High School Musical' into a musical?

Ignorance is indeed, bliss.

Knowledge and taste, May you rest in peace.

I feel your pain. Still, modern cinema is a strange animal after all.
Its not just musicals. Look what passes for action/horror and comedy these days.
Speaking of musicals, I viewed 'Bedknobs and Broomsticks' and 'Little Shop Of Horrors' yesterday. Nostalgic bliss. I love 'Labyrinth' too. Not sure if that counts as a musical though.
A musical is a film where the characters emote through songs and Jareth in Labyrinth clearly does that.

Modern cinema is a repulsive animal.

I agree with you, completely.

Anything can pass of as anything as long as it is categorized into a specific genre. If it says "horror", people will believe it is indeed a horror.
It's kind of like the placebo effect in many ways. I've been wanting to see 'Little Shops Of Horrors' for a while now. I'll be sure to give it a watch.
