In the overused Minato vs Itachi debate threads, I always take Minato's side, but I am a fan of Itachi regardless of that.
I like Itachi's moveset and how smart he is, the tools that he possesses are really powerful.
But I dislike how heavily he relies on genjutsu. He's also got his share of character flaws that I dislike... like believing that revenge is the right way to make his brother stronger. Also dislike his overconfidence and the hypocrisy and lies he spews. But he's necessary to the story for all of that so I respect who he is to the show.
