In this week's episode, Obi-Wan and Anakin board a Separatist warship in order to rescue a Republic government official. General Grievous battles Obi-Wan, but when the ship begins to go down, he flees the ship in his personal starfighter. Sound familiar? That's because it's point-for-point exactly like the opening of Revenge of the Sith. Just switch Palpatine for Padmé, exchange elevators for trains, and remove the duel with Count Dooku.
The plot of the episode has no twists or surprises whatsoever because this story has already been done before. What's worse is that it's a letdown as the final part of the Malevolence story arc. The Malevolence was essentially beaten in the last episode; its demise here is rather unspectacular. It literally is gone in a flash from a long distance away. No big explosion (that we can see), no nothing.
If there is a bright spot in this episode, it's the reunion of R2 and 3PO. Anthony Daniels lends a perfect level of authenticity to the duo, and it's fun. But it's ultimately a short bit that lasts less than 30 seconds in a 22-minute story.
This isn't a terrible episode, per se, it's just very by-the-numbers and not at all special.
