RE: them showing LEGALLY BLONDE on MTV. I think it's an interesting experiment for them to try. If the kids who are obcessed with shows like HIGH SCHOOL MUSICAL will watch this show and want to see it, then i think it could be quite successful.
Also, re: RENT the movie. I still don't get that one. The movie is not the show. If it was your favorite movie, how could you not want to see the show live? (although without the OBC it's not the same, but still).
