I had a friend that linked the first episode to me (because after four episodes he became a brony), and I disregarded them. A week later I went to YT and watched them, and got insta-hooked. xD
And yeah, Season 3 Episodes 1 & 2 were pretty good!
Spoiler:
To be quite honest, most of the action happened in episode 2 than in episode 1, when I was expecting most of the action to happen in both episodes (just like the previous events like Discord and the Canterlot Wedding. I mean, that's just my opinion though).
Though, it was great to see Cadence and Shining Armor appear in this event once again. And great to see Spike saving the day!
I found a gif that represents my favorite moment of the episode. Silly Pinkie. xD
