I've been eagerly awaiting the dvd release of this series a while now, having dipped in and out of the show while it was being broadcast by the Disney channel.
I sat through the entire series in just one sitting. That's how much I loved it! Each episode is fun and action packed, with a LOT of humour. And it's not just aimed at kids. It's something that the whole family should enjoy. I'm 20 and during some sequences, I was in stitches. The characters are great. There's also not a single character in this show that I dislike, which is quite hard to achieve.
So yeah, I'd say go for it. It's also really cheap in comparison to everything else that's out at the moment. :)
