The question should be What DID you like about ROTS.
I liked the duel between Mace and Palpatine.
I liked Hayden Christensen’s face acting
I liked the Order 66 scene (except Anakin killing children)
I liked the final duel between Anakin and Obi-Wan, despite it being a CGI fest and being over-the-top.
That’s about it really.
