Regarding Legally Blond? It helps if you loved the movie, a lot. (I didn't - the movie grated on my nerves and the musical even more so). It is cute, I'll give it that and the guy who plays the love interest/hero is actually sort of adorable. But the music is grating and one note. The lyrics are :

To hell
I'm with Elle

or

Life will be swell
I'm in the hands of Elle.

It's very repetive and has simplistic rhyme schemes. Feels very amateurish. Don't bother with it. Hopefully the next musical MTV puts on will be a lot better.
