Finally we've gotten back to the series and what a way to start. Two episodes in price for one.
Grievous returned and its a great thing. Nineth is a very good episode and especially since Grievous cleans up the reputation he gained in my eyes during first season as the regular cartoon villain who is always beaten. Grievous has become evil now, like what all the hype before ROTS came out made him to be. If you liked Grievous in season 1, you will love him now. Very action filled and exciting episode overall. 
I also noticed how the music resembled a lot like the OT music during this episode. You know what I mean when you hear it. 
Tenth episode picks off right away from where the 9th episode ended. Its a bit slower episode but not any worse than the previous one. Overall its been two great episodes.
