I promised I would give my judgement after I had watched the finale. Time for my judgement:
Aside from the fact that the episode was a little rushed , I thoroughly enjoyed it. I liked (most of) the songs, the set up was alright, the writers handled it all pretty well (M.A Larson wrote the episode - what did you expect?) and holy shit is that Derpy in the background there at some points?!
Sure, they weren't very clear on certain things, e.g. is Twilight immortal now (she's certainly taller like I anticipated would happen), what is she the Princess of (Magic is probably it, but hey...) and, most importantly; where and how will things go from now on ?
"Everything is gonna be just fine!"
Yes, what the new Princess of (supposedly) Magic said. I'm really excited to see where things go in season 4 (I saw somewhere Tara Strong mentioning Twilight staying in Poynville - but of course; it's Tara Strong, you never know with that one...)
So in conclusion:
I could have saved myself all those hissy-fits I threw a while ago. Twilight Sparkle is still my favourite pony (probably more so than before). I'll anticipate season 4 with glee, and I'll definitely still be staying - I believe it will definitely be worth it.
I'll be waiting, Twilight.
