Presumably some kind of arc will materialise within the series, but the first two episodes could be watched in an order and are completely independent. One episode, Ambush, focuses on Yoda and his fighting abilities (he's very hard) and the other, Rising Malevolence, on a rescue mission by Anakin and Ahsoka.
What the CGI is extremely good at visualising are the spaceships. Greivous's massive flagship looks, well, massive and menacing. And the Republic gunships still roar past and look like fighting machines.
Adults may get annoyed at the Battle Droids, who talk to each other in (rather feeble) comedy sketches, but this is a programmer for kids, and I wouldn't like generalize and guess what they think.
Overall, I enjoyed them: bitesize, action filled chunks of Star Wars.
