Glee is art because it's singing and all about expressing yourself through music and being able to be yourself weather your judged or not. But it does have other factors in it like school and real life teenage drama, but the business part of it is that they sing songs that most of the world has already heard and like, so whether you watch it for the first time or have watched from beginning to end you're able to some what enjoy it because you know the songs.
To me I get really emotional on this show because besides the music part of the show they deal with real life teenage issues and they don't sugar coat it. Like with having a gay couple (Kurt & Blaine) on the show they really get into showing the real life struggles of being a gay teen and for me it always hits a spot because this happens everyday in high schools.
Glee's style is different because it's kind of nerdy, but at the same time cool and it's more of just being free and instead of putting in your typical you're popular "I'm better than you" act they put in different types of people, overweight people, gay people , average people, cheerleaders and more. The meaning behind this show is you should be able to be you and achieve your goals no matter what and that singing isn't a weakness if anything it makes you stronger because you're able to sing whenever and wherever music is a form of freedom.
