I've been watching FiM since the series started. I love it to pieces.
Admittedly, I never liked it much as a kid. The original show was garbage meant only to shovel as many pallet-swapped ponies as possible on young girls. I never owned a single toy related to it.
But this new series? Man, it's everything a cartoon should be. It has adorable art, and actually has real characterization and stories to tell.
I seriously need to find some plushies to buy... especially Rainbow Dash. Who is obviously Best Pony. (Preemptive strikes FTW)
