There’s a scene literally from Revenge of the Sith in there! Mace saying “I sense a plot to destroy the Jedi” in the war room happens like ten minutes before he goes off to arrest Palpatine. Also Padme is visibly pregnant and Anakin doesn’t find out until after Dooku is dead.
I was under the impression the last we would see of most of the characters is just prior to the Battle of Coruscant, so this is cool.
