Well, this was quite an eye opener in several ways. It must have been quite a good episode you chose to show off.
Back in 2009, at a time where I hadn't seen a single life sign of My Little Pony in four years, and when Horseland ran before Pokémon Diamond and Pearl on Saturday mornings, Horseland felt very generic to me, as it was very similar to every other horse show I could receive on Nordic telly in that a lot of focus was on the ties between the horse and its rider. And back then, I perceived Horseland as being heavy on teen romances, but looking at this episode now, I can't remember how I even reached that conclusion.
It seems heavy on morals, and heavy on friendship, both of them so much that I struggled to keep my attention on it (skipping parts of the ep haphazardly). But if any other episodes have that mythical or epical (not necessarily epic quality-wise) flair over them, perhpas I can no longer speak as negatively of it as I've done in the past five years.
