Oh man, what do people love about MLP:FiM... well, the characters are all really good. Almost everyone has a favorite even! The music is also really good, if you've only seen the first two episodes then boy are you in for a treat once you get to S1 E11 and onwards. The storylines are also pretty relatable most of the time, especially S1 I'd say in tthat department. There's definitely a lot more to it, such as every season having a slightly different feel(which you do not get with a lot of other kid's shows mind you, at least not always in a good way like here) but you really just gotta keep watching the show to really dive in to that stuff. Cheers!
