I didn't really like it.
Most of it centers around the "Mysterious Mare-Do-Well" herself, in that it was obvious from the moment she appeared onscreen who it was. I was expecting a new character or something, but then again, in the context of the actual episode, it makes more sense this way. Still, kind of a let-down, personally.
It was also kind of pathetic that Rainbow Dash tried to do "heroic deeds" just so she can be praised. Now if anything, THIS is the kind of lesson that should be learned from that Fairly Odd Parents episode. But at the very least, at least she didn't try to create a crisis just so she could play the hero...
TWILIGHT!
Really, though, the episode's kind of boring. Once I realized who the Mysterious Mare-Do-Well was, it was only a matter of waiting until the very end for the "shocking reveal" and explanation of who did what. Still, nice to see Rainbow Dash learn some "grace and humility", as Twilight put it.
Actually, what I found rather interesting was that the first time Rainbow Dash saved the day, she seemed to be all shy about it. Kind of like how Applejack mentioned she's the only one to every pull off a Sonic Rainboom, or when she won the Best Young Flyers Competition. It wasn't until the second day-saving that she really started soaking up the attention. It's neat how, even though this is a Rainbow Dash-centric episode, it's less about how awesome Rainbow Dash is, but more about how she really needs to keep her hooves on the ground, which is a lesson she probably should have learned a while back.
One last thing I'd like to mention. The mention of the Pinkie Sense... made me cringe. I like how they didn't completely forget about that particular power she has, but at the same time, I hate being reminded of that episode. Not to mention, shouldn't her Pinkie Sense have told her that Rainbow Dash was about to jump on her?
Either way, Pinkie Pie at the end was probably my favorite part of the episode.
