as long as you don't even defend it and just hide behind the word "opinion", no-one is going to take this series seriously.
Would you like me to create a 20 page essay where by I discuss the awesomeness and sheer brilliance of Sola to sway your distaste for it? Will this bring you to your senses and thus realise the greatness that is Sola? No, sir, it won't.
The fact of the matter is, even if I stopped using the word "opinion", it wouldn't change a thing. You've stated that you don't like it, nothing will change that. Its your "opinion" you don't like Sola, it isn't fact.
I can't deny that anime like Sola aren't exactly scarce, and they may get repetative at times, but the fact is I like them regardless. I don't care if you despise them, and you shouldn't care I like them either (or anyone else at that). This type of discussion could go on for yonks and nothing will come of it.
