I believe that positives and negatives earn your rating...
Positives:
-Plethora of Anime choice
-good quality streaming (and my internets trash so thats pretty good)
-ads aren't terribly long
-updates shows relatively quickly
Negatives
-Offers "14 day trial" but requires card information
-Requires Credit Card for premium smh
-Ads occur way to often throughout shows
-Ads are made long by colliding 3 together, 2 of which are usually the same
-(Some) Ads are way too $#*!ing loud
