Oh boy, this was one of those episodes. Yeah, yeah, Applejack saved Spike's life and now Spike dedicates his life to Applejack. I have seen this multiple times and it is always the same. Yeah there were some interesting moments, like how Rainbow Dash has moved from reading to writing. The animation on the Timberwolves was amazing, it is cool to see that in a kids show.
The story though just sucked. I thought we might get something interesting, melding Spike and Applejack together, but sadly we didn't. Spike was turned into a klutz, which I have to admit was out of character for him. This could have been a really fun and sort of dramatic episode if done right. The whole owing a favor to someone can be done well, the show Arthur did it beautifully, so why can't My Little Pony get it right?
Ah well, an average episode, nothing special to it.
