First, my complete and comprehensive analysis of the new trailer for the MLP movie:
Carrot Top confirmed! There was probably some other stuff, but why focus on the negative (no really, please don't ask me bitch about everything I don't like, or I'll never stop)? Let's instead take a moment to acknowledge that, no matter what else goes wrong, there will be at least one reason to watch the film.
But for now, let's focus on the fanfiction side of the pony equation--and, in keeping with our best-part-of-the-trailer theme, let's make it another Carrot Top edition! Well, an edition of stories wherein Carrot Top is one of the tagged characters, anyway. Head down below the break for my thoughts.
The Bet, by King of Beggars
Zero-ish spoiler summary: Rainbow Dash is standing around out in the fog, staring straight ahead. What could it mean?
A few thoughts: There's nothing more here than meets the eye--a bet collides with some townspony over-reacting--but it's funny enough for what it is. There's a nice flow to the panic-conversation, and the reveal at the end of what was at stake is amusing (if, perhaps, a bit too extended for what is really just a reveal). With that said... there's not a lot to say.
Recommendation: If seeing Carrot Top and company make hay about zombies, reverse-zombies, and the like sounds amusing to you, this provides above-average delivery of that kind of humor. But if you're not in the market for "that kind of humor," there's really nothing else here.
The Rose Garden, by TheManof2481
Zero-ish spoiler summary: Roseluck's diary, in which she recounts bonding with her new special somepony... and preparing to show her the special connection Rose and her friends have with flowers, a connection beyond what ordinary ponies can comprehend.
A few thoughts: The editing on this is a real letdown. I suppose one could argue that it should be interpreted as in-universe capitalization, punctuation, and basic sentence structure issues, but the fact is that this story is poorly constructed to (and well past) the point of distraction. Then there's the question of the format itself; while the diary does largely avoid the most obvious cheats (crossed out words and the like), it does indulge in a lot of detailed conversations which I didn't always feel Rose would be likely to transcribe in their entirety, as well as having her explain a few things transparently for the reader's benefit. It's a pity, too; the vaguely Lovecraftian angle (in terms of tone and horror, not tentacle-monsters) is kept appropriately opaque right through the ending, and at its best the story does manage to be downright unsettling.
Recommendation: This is a good choice for readers who place concept over execution; there's a disturbingly uncertain cosmic horror story at the heart of this, and even through its flaws I found bits of imagery memorable. That said, there are plenty of flaws, and anyone who's going to get bogged down in the presentation should probably pass on it.
Forecast, by Jondor
Zero-ish spoiler summary: Rainbow Dash and Applejack are on the verge of becoming an item, and the rest of Ponyville's farm/garden community is terrified that AJ will get preferential weather treatment. So the order of the day is: sabotage!
A few thoughts: Although "shipping" isn't really a thing that appeals to me, I can appreciate that this has a nice balance of shipping (not really romance, but the "main six gonna kiss" sense of inevitability which is the hallmark of a shipfic) and humor. Also on the subject of my biases: it may be my biases, but Carrot Top is particularly entertaining as an aggressively misinformed but undeniably earnest worrywart, and the other characters fill their roles well. That said, the story does feel a bit bloated; at over 7000 words, this is pretty long for something as light and goofy as it is (not helping: the entire plot is "Dash and AJ might try dating, other ponies try to interfere, fail;" there aren't any meaningful subplots which could put some more flesh on that bone), and it ends up repeating some of its better jokes well before it wraps up.
Recommendation: If you enjoy shipfic-with-antagonist humor (e.g. "the hilarious misunderstanding," "the winkingly pressaged karmic retribution"), then give this a try. It's probably not for people bored of those particular cliches, though, nor those wary of seeing ideas beaten into the ground.
