No matter how great the things that bronies come up with are, there's always someone doing something even greater and even cooler.
I finally got a chance to watch it now. The verdict? Applebucking-lutely amazing.
Really, it's hard to praise this too much; I think it's entirely fair to say that the level of quality displayed here is approaching that of the show proper. I'll grant it's not entirely without room for further improvement – the pacing could've been tightened up, the end was a little abrupt, and some of the references that were a little too obvious and distracting, but all in all? I'd not have thought it possible for a fan project to do this much, this well.
Kudos to everyone involved; you have every right and reason to be damn proud of yourselves.
