Austin & Ally is a great show for children and teens alike, combining the fun and silliness of the characters kids like, the romantic relationships teens like and music - something everyone can enjoy.
While Austin is an outgoing, fun and insanely talented guy and Ally is this quiet, smart and also insanely talented girl, the unlikely - though extremely Hollywood - pair make it work.
As I am a big fan of the series, my rating may be biased. However, I don't think I'm wrong.
It's somewhat educational as it teaches kids life lessons about relationships, lying, stealing, etc. It also faces the reality that there will be people who will try to hurt you in life, but it writes a way to help deal with it.
Also, very recently, it literally saved a young girl's life because of some information it gave about bears and how to stay safe in case you come face to face with one.
I think that between the realism, quirkiness, hilarity, music and encouragement to be yourself as the characters do, the show is great for kids to watch. Even adults can appreciate it.
I hope to see Austin & Ally get a few more seasons after season 3.
