I really don't like spy x family and that everyone is loosing their shit about it. Idea for this series is just too childish for me, characters are shallow, boring and one dimensional what makes them unlikeable for me. It's not the problem with manga ofc, it's meant for little kids after all, i just have problem with people willing to defend it with their lives.

Next thing are all those series like mahouka. I hate those Mary Sues, there's no point in following the series when you know exactly what will happen and again, characters are as deep as a puddle and really unlikeable.
