How do you rank your MLP episodes?

I assume that most everyone uses a system from one to five, but what that entails can be very different from person to person. For instance, here is how I rank my episodes;

* means that I couldn't watch the whole episode without cringing.
** I watched the episode but I don't want to watch it again.
*** I could see the episode again, though reluctantly
**** The episode was good overall and I would watch it again.
***** The episode was awesome in everyway! (not many episode receives this ranking)

Some examples are;

* S1E6 Boast Busters
** S1E2 Friendship is Magic part 2
*** S1E3 The Ticket Master
**** S1E5 Griffon the Brush-off
***** S1E10 Swarm of the Century
