Its probably going to be decent enough for us :) why not a perfect score? well,its because they might be getting low of ideas for each episode resulting in not-so-good-anymore material
With some spoilers leaked, it's gonna at least be decent. I did like (or, am liking) S4, but not too much to give a 10 out of 10. It'll be interesting to see Pinkie's new attitude when she gets a coltfriend, and.. well, not so sure about Kimi Sparkle getting on, but I'll take it for FiW.
