I liked them both.

I thought the cave scene with Yoda and the Clones and the Plo Kloon episode where he does about the same thing goes out of its way to show that the Jedi really care about these Clones and aren't going to throw them around like battle droid pawns. Thinking that these same Clones will eventually turn on their Jedi just because they are ordered to hurts a little.

The prequels, besides explaining too much about where some things came from, also in parts didn't explain enough. We were forced to assume since Obi-Wan had cute names for a couple of the Clones that they were actually friends. Now with these episodes and the movie we see that they worked together and respected each other greatly. Also in the Plo Kloon episode, we got to see Palpatine personally contact Anakin after the Jedi left his office to give him some friendly advice, again something only casually mentioned in the movies.

I really think this series might actually do what is advertised and be an entertaining fill-in to the space between Episode II and III. Should we have needed it? No. Is it welcome? Yes.
