Pony General:"Season 12 will never air" edition.

Hooray, I watched it.

Post-Season 3 Fan Episode 1: Double Rainboom

 Spoiler

I really enjoyed watching it all. The animation is scarily amazing, and the PPG cameo made my day. Now onto some nitpicks:

-I think they could have done without the meme faces. It kind of drove me out of thinking it could be an MLP episode.
-Rainbow Dash felt like she got added a huge dash (buh dum tsh!) of Pinkie Pie into her character. In the beginning up until she started flying at super-supersonic speeds I thought it was Pinkie Pie instead of Rainbow Dash

Other than that, it was a fun watch. Inside jokes like Derpy and Dr. Whooves were nice without making it too obvious. The only one that felt forced was Snowflake/Roid Rage. Being one that watched PPG, the 2nd half was just awesome to watch. Some may complain they were being too brutal to the monster, but if you think back it's quite common of them to rip and destroy monsters that invade Townsville.

Animation: 9001/10 Definitely it's strongest suit
Writing: 6/10 Characterization made it too easy to know it's a fanmade work. However, it's still an okay story if you look at it from a "shenanigans ensue" type of story. She got off pretty scott-free for nonlethally nuking all of Ponyville with her antic.
Moral: 7/10 Could have been worded better, but at least Rainbow Dash sounded like she learned her lesson
Authenticity: Again, you can tell it's a fanwork. It won't fly as a canon episode.

Enjoyment: 9/10
I won't let glaring issues like the writing stop me from enjoying the amount of work that was put into the episode animation-wise. Here's one way to look at it. Get down the animation, you can then focus more time on the story. There's still loads of potential from this Pony fandom, and I'm proud of it. I can imagine someone in the future will improve upon the works of Double Rainboom, and create an episode that's not just matching the animation but also give a story that would sound just like an actual MLP episode.
