What I liked:

Ewan McGregor

Liam Neeson (for the most part)

Ian McDiarmid (until his transformation scene in ROTS, anyway ...)

John William's score

The idea that the Jedi order isn't an order of perfect, pristine monks but an order of corrupt, dogmatic fools.

Darth Maul

Darth Maul's lightsaber

The duel in TPM (though it does get a bit too flashy after Qui-Gon leaves the fray)

Mace Windu's lightsaber (his purple blade almost makes up for the monotony of the other lightsabers)

That Anakin's lightsaber was blue in his duel with Obi-Wan on Mustafar (this is the only and only thing I expected to see in the prequels that actually came to pass)

Watto

Dexter Jettster (bad CG aside, I like his design and personality)

The aesthetic design of the Kaminoans

The aesthetic design of Padmé's silver starship in TPM (the other ones in the other prequels, not so much)

The aesthetic design of Grevious

That's about it, unfortunately.

Fixed.
