So, to stop being a pony-hating hypocrite, I actually tried to watch some of the show. I made the unfortunate mistake of watching the first episode, so after about 40 seconds of ridiculous back-story about winged unicorns pulling the Sun or something, I stopped.
But then I watched a clip from the show featuring the ditzy pink and broody purple pony going about what I assume are their typical antics. It was funny, but really nothing that would demand a second viewing of. Were I a 4-year old girl and not a neck-bearded young man, I think I'd be more enthusiastic.
Besides, I have reruns of Space Ghost: Coast to Coast and Home Movies to keep me entertained.
