opinions are subjective and despite popular conception this does not mean that they are infallible
when I say you have a bad opinion I'm not saying that your opinion is clearly wrong or something, I'm saying that what your opinion is made of does not really make any sense
for example, the part where you said that the music was just rehashed from super mario galaxy, or where you said that you enjoyed mario galaxy, but mario galaxy 2 was "stale" - even though critical examination of those games reveals that super mario galaxy actually reused more music than super mario galaxy 2 (or super mario 3d land, for that matter), and that super mario galaxy actually took less innovative design risks than super mario galaxy 2 did, which would therefore make mario galaxy 2 the one that is the least stale in the list of entries used in this response, which would therefore make your statement that 'galaxy was at least refreshing' sort of invalid
which would make your opinion invalid
I mean it's your right to be able to have that opinion, but it's kind of stupid to say that "nobody with an ounce of intelligence would say something like" call your opinions bad, because not only does it imply that you don't know what subjectivity is, but you're also being a hypocrite by insulting somebody for disliking or disagreeing with your opinion - even though that's just, like, their opinion, man
