No one is turning your opinions around, If that's what you meant.

The three tomoe Sharingan already has a powerful genjutsu but it also has to be met with eye contact.

Yes, Sasuke was blinded by hatred, but it didn't blinded him enough to try to kill Itachi at very sight like his 12 year old self which even the latter had noticed and commented on. instead he didn't try to kill Itachi and instead threatened him to name the guy who he correctly speculated to help him in the uchiha massacare. He was still able to do as he planned and overcome most of Itachi's technique other than Susanoo.

And the Sharingan, is a powerful tool of analysis, giving the user perfect clarity in perception and with Photographic memory. His sharingan should just notice it which it did and because Itachi tried a whole realistic genjutsu on sasuke instead of the Torture version it just explains that Itachi did not want sasuke to break through or notice but he did.

Don't remember CM in as part of it but if you didn't notice, the possesion was taking over Sasuke's whole mind and then he just changed the whole dimension with his will power. Orochimaru never thought that anyone could escape that jutsu let alone possses him with it. I highly doubt if there was anything the CM was helping for Sasuke in there. Since CM is already something Orochimaru can see through since he's thec one who created it.
