Well, we've already reached the halfway point. Now, I should sum up on my thoughts on the 1st half of season 4:
- Princess Twilight Sparkle: Great start.
- Castle-mania: Impressive theme.
- Daring Don't: Fun, and I guess Rainbow Dash's fangasming is not the same as mine from the time I met Rob Paulsen.
- Flight to the Finish: 2nd best Scootaloo episode plus a great song.
- Power Ponies: BUCKING LOVED IT!
- Bats!: Good morals, good song, good story, nothing more.
- Rarity Takes Manehatten: Great story period.
- Pinkie Apple Pie: Awesome song and good plot.
- Rainbow Falls: It's not too bad; but, hey, I've seen worse.
- Three's a Crowd: Discord is just as much of a riot as he was in Keep Calm and Flutter On. I wasn't expecting Discord to have a song of his own at all.
- Pinkie Pride: Weird Al Yankovic is awesome.
- Simple Ways: Not bad.
Those are my thoughts. I'm sure yours are different.
