Never understood why it was accepted that you need a sharingan and the same blood as Itachi to break out of Tsukuyomi.

The power of Tsukuyomi lies in time dilation. If you can freely manipulate time, to mentally break your enemy before they can break out. It's a battle of speed essentially. The Tsukuyomi used on Sasuke (second time) appeared to have no time dilation, so Sasuke could break out.

There was a previous thread that broke it down nicely and explained it step by step. I'm probably butchering it now.
