So, there was one more thing about the season finale that I forgot to mention in my initial reaction blog post (found here: [link]
), which didn't quite pass the sniff test but it took a little longer to sink in. I figured the most effective (and entertaining) way to describe the problem would be via a comic, so here you go.
Basically, the second half of the episode more or less negates the message of the first half, and that kind of rubbed me the wrong way. Maybe I'm not giving the writers enough credit, since for all I know this could be a very important part of the supposed Princess Twilight three episode arc that Meghan McCarthy mentioned, however at this point, I can only really judge the season finale as a single episode.
SPECIAL THANKS: Deviant BeltedYapper suggested the song "Free Will" by Rush as a companion to this comic. It even mentions Celestia (sort of)! Listen to it here: [link]
