I kind of fall into the "Rainbow Dash" rate on the scale. I just don't see why we (men) like it so much.
Well, there's a number of reasons I like it.
#1: The characters are lovable, and not ridiculously cliche. And any that are cliche, like Pinkie Pie, are so intentionally off the deep end that it's just funny.
#2: The stories are filled with good, clean humor.
#3: The messages are overall very good, and sometimes the very things that need to be taught to the average kid nowadays. Sometimes I'm impressed by the forcefulness of some of them.
#4: The characters are very realistic for the most part, and remind me of people I know and love in real life.
#5: The stories are usually fairly original, and well written.
#6: Art wise, the show is well animated, and very appealing to the eye. Yes, even with all those pinks and purples.
I'm not one to jump on bandwagons very often, so it's surprising that I liked it so readily. To tell the truth, it's one of the only shows I've EVER liked. I hate modern TV.
