People are allowed to call a series anything, whether it's "one of my favorites" or "top 20 shittiest". Even things like "objectively bad". Neither of those three things are an indication of reality, but of the way that person thinks based on how he was raised and the things he has seen up until now. Sure, the world would be a less complicated place if everyone everywhere started every nonfactual sentence with "in my opinion", but that would be both tedious and redundant. It would be much easier to just assume that anyone having an opinion is, in fact, just having an opinion. It will save you a lot of headaches.
