@worst episode discussion
I meant to reply to this earlier, but I thought my least favorite episode would be one of the Applejack ones that I didn't even bother watching all the way when they first came out.
Well to my surprise I finished watching them recently and I was wrong – my least favorite episode is still Crystal Empire.
I usually feel kinda crappy about being hard on the show, but I watched this episode 3 times and I can't help but hate it.
I think a big problem with these episodes is that the crystal ponies are so boring. Sure they're supposed to be sad sacks without the crystal heart powered up but it goes beyond that. Not only are they drab husks throughout most of the Mane 6's adventure, the crystal ponies (with exception of the librarian) all shared from a pool of like only 3 cutie marks that were used over and over again.
This was pretty disappointing to me considering how unique looking background ponies can be and how only the librarian got characterization (if you could even call it that).
Twilight's little song and dance with Spike towards the beginning was kinda unnecessary. It was already established that she was worried about Celestia's test at the very beginning of the episode and while it was nice I couldn't help but think that time could've been better spent.
Sombra was a pretty boring villain to start a new season off with (he was kinda like watching a shark behind glass most of the time) and it's also odd to me that they didn't just have Shining Armor powering the barrier that was keeping him out of the Crystal Empire from the beginning considering we can surely assume his cutie mark means his special talent is protecting ponies with magic like he did in Canterlot Wedding (and that he probably would have been better for the job). Instead he got his horn all messed up like 8 minutes in. You'd think the Crystal Empire would have had guard ponies before Equestria Girls who could have handled scouting and recon missions.
The evil door thing kinda also struck me as a waste of time (and even more so when they dragged Spike into it) because again, we already knew Twilight doesn't wanna let Celestia down.
To summarize I think the Crystal Empire episodes could have been better if we at least met a couple more unique and characterized crystal ponies along the way and they omitted some unnecessary things to allow more time for a more satisfying adventure.
I liked a couple of things about this one though. It did give us special eyes
and Rainbow Dash nomming corn.
But I actually liked more about Equestria Girls. So to me the Crystal Empire is definitely worst.
