A more interesting question to me is what the prequel actors thought of the prequels. I highly doubt that Hayden Christensen gives a s$*t about them, and Natalie Portman is in no way, shape, or form a fan of the series. In fact, she never saw the originals before her performance in Episode I and I personally doubt that she ever took the time to watch them (*cough* stuck up "Indie" starlet *cough*). It's well known Liam Neeson considers Qui-Gon to be one of his weakest roles, and Jake Lloyd definitely suffered years of torment, abuse (and reportedly small royalties) from being little boy Anakin.

Even MORE interesting is what the OT actors who also were in the PT thought of the Prequels. As Evan1975 already showed with Anthony Daniels, even he, a constant of the entire "saga", has negative words against the PT, which I personally found shocking! I feel that Ian McDiarmid mostly enjoyed his greater (and arguably more "serious") role in the PT than his one film appearance in "Jedi". Deep down, I reckon that Frank Oz probably didn't enjoy the PT as much, since he lost the physical acting aspect with the move from the puppet Yoda to his CGI "successor" after TPM (and now the Yoda puppet in I has been erased in the vein of Sebastian Shaw's Old Anakin and Clive Revil's Original Emperor!).
