I'm pretty much the same way. It lures you in with one episode, you end up watching several. As for the ponies, they are all so likeable that it's almost hard to pick just one favorite. Of course, once you've decided on a pony, there's going to be a time another pony may take the top spot. There was a time that I though Pinkie Pie was one of the most annoying characters ever, but she eventually became one of my absolute favorites.
