Never watched it on cid, thankfully.
I cant imagine a bright blue robin williams more befitting a drug experience though.

Thing is, Aladdin was really meant to be a musical from the start, as opposed to an animated movie with a dance number added. So at least it makes sense.

I was never really a fan of musical numbers in movies. There are a few exceptions, like Ursula's Poor Unfortunate Souls or Christmas Present's song in the Muppet Christmas Carol, but for the most part they're a waste of time and don't really add anything to the films. Even as a child I found them really irritating and often fast-forwarded through them. Thankfully they seem to (mostly) be a thing of the past nowadays.

HEEEEEEELLLLLLLLFFFFFFFIIIIIIIIIRRRRRREEEEEE!!!!!

The problem is that it isn't only Dreamworks who makes them. Despicable me was made by universal and Star Wars: Detours is Lucas Films. They probably just made a trend.
I actually think that pop culture references can be pretty funny and if they are not the main thing in the movie or in a scene, it's only an ekstra layer, in the silly dancing scenes there are no layers- they are not like onions- it's pure nothing and totally without meaning.
I also see why some people can't stand songs in movies, though I can actually live with them, especially if they are great. (I once had almost a full day of "A whole new world" from Aladin) On the other hand, musical is realy not my thing. Way to often I have had the feeling, that the music was getting in the way of the story and the caracters.

That's probably the biggest reason I have little love for Dreamworks's flicks. They have a knack for overdoing it in pretty much all of their films.

The first Shrek was pretty good I think. It was funny even if you didn't know many of the references and they didn't overdo everything. Afterwards it seems they have, sort of "developed" their style for the worse.
