I thought Ian's performance was right where it needed to be. Enjoyed the kindly senator of ep 1 and the crazy emperor of ep3. The 'no! No! No!' line was delivered so creepy and i thought it was awesome! I'd always know palps was the sith emperor, but when i saw the palps the senator performance of ep1 it had me confused. Maybe there's a twist or maybe i assumed wrong all these years. Ian played the character very well!
