when i first started liking itachi i was on the totsuka/yata banwagon, but then as i begin researching the character more, i'd realize that his genjutsu feats(koto included) is much more impressive, especially that time-tsukuyomi. it's underrated and due to the lack of genjutsu being rarely shown in the series in comparison to nin/tai, it fell under the radar, but the truth is, genjutsu especially itachi's in particular is just as OP if not greater than the high tier jutsus, some people began to pick up on this which resulted in certain anti-uchiha fanboys try to find ways to deal with gen (speed/sagemode/no eye contact). but they don't realize is that with itachi, his feats with gen isn't how OP it is(well, it is) but how it's used. ie: catching someone off guard w/ gen. even the weakest gen can change the course of an heated battle (sasuke v danzo), so just imagine from someone who can cast gen w/o being sensed, with a finger and other means besides eye contact. the whole koto and izanami is just the icing on the cake.
