I have to be honest here and say this one totally lost me.
I totally stopped caring about half-way through. I started doing other things and really didn't pay much attention to the end.
The song was kind of derivative and shallow. And the plot was just way too forced.
Really I think it might have been one of the weakest episodes of the series and a waste of the CMC.
Aw. Ah well, hopefully you'll like next week's episode. That's the "Power Ponies" episode!
