The characters are so diverse, from the stud of the football team who enjoys singing and dancing (Finn Hudson) and faces criticism from his football mates to the geeky good girl that is not afraid to speak her mind and reaches for her dreams (Rachel Berry) to the School Counsellor with OCD who is in love with a married man and faces mind-boggling decisions regarding her future (Emma Pillsbury) to the Physical Education Teacher (Sue Sylvester) that is the antagonist of the show and together with her cheerleader minions they come up with diabolical plans to bring down anything in their way.
The tag line accompanying the poster writes "A biting comedy for the underdog in all of us". I think everyone can relate to the show one way or another. It speaks about how people can at times hide things about themselves at the expense of wanting to be liked more by their peers.
In addition, it teaches us to come out of our shell and live life being who we really are and doing what we enjoy. Experience with the cast how they live their lives through the highs and lows and being genuine to themselves. By doing so, I believe you will live a happier and healthier life. Stay tuned for my Video Clip On Demand for Glee in December.
