) I can safely say that My Little Pony: A New Generation was great! 
And here are my random thoughts:
MLP Season Three episode rankings (updated 6th Dec 2019) · 1:46pm Nov 3rd, 2015
0/10 - AWFUL (unsalvageable, nothing to be gained from watching it, never should have been made, wouldn't recommend to anyone, completely butchers an important subject/teaches a horrible and downright toxic moral)
1/10 - HORRIBLE/BORING (tedious to sit through, hurts to watch it, a bore, no reason to watch it, whatever positive things about it are tiny and not enough to save it)
2/10 - VERY BAD (slightly less terrible, maybe it had that one character you liked or one/two jokes you laughed at that kept it from being a 1 but still very painful)
3/10 - BAD (the kind of bad where you're checking your watch over and over to see how much time is left before it finally finishes)
4/10 - MEDIOCRE (not awful but not really that good either)
5/10 - EH (average, didn't love it or hate it but you feel like you could've done something better with your time)
6/10 - DECENT (the first positive rating on this list, fine overall, you wouldn't watch it again but you are glad you saw it once)
7/10 - GOOD (enjoyable enough that you'd maybe watch it again in future, had some noteworthy flaws but is overall a worthwhile sit-through you'd recommend to someone)
8/10 - GREAT (a solid, enjoyable episode, very entertaining)
9/10 - EXCELLENT (very engaging, awesome, you really recommend it to anyone)
10/10 - MASTERPIECE (extremely engaging, teaches a valuable moral perfectly, definite must-see for anyone)
