Well, you kinda have to make your own judgement when you first watch the show (as in a couple full episodes.) I for one have always been a fan of Cartoons and Animation, and I remember watching the old movies when I was younger. They weren't bad, but they didn't really hook me. But I did gain a sense of not being totally new to the genre.
It has excellent voice acting, round lovable characters, great animation (with it being animated with Flash and all.), and a great way to learn some good old fashioned morals and lessons which seem to be almost non existent in other cartoons. Lauren Faust has always done a great job with cartoons going all the way back to The Power Puff Girls, which was one of the best Action cartoons when I was a kid.
You can argue that we're not it's intended main demographic, with it being made for little girls. But I see it as a way of rebelling against social norms. Women can play football, have seats in politics, and basically everything else in society women can do. But heaven forbid the day a guy enjoys a quote on quote "girly" Cartoon.
It's a really nice show, check it out when you can. Peace.
