In this review i will break it down into storyline, characters, and overall Storyline: The storyline was pretty simplistic. Yoda has to negotiate with Watto's race for a republic base. In order to do that he needs to pass a "test" of count dooku. The storyline is simple and lacks anything more than that simple premise but for Yoda's introduction, it works well because it brings out what a great Jedi Master he is to overcome the odds.
Characters: Who doesn't love Yoda? This episode once gain shows Yoda's ability to Mentor others (as a teacher) and also his ability to use the force (when he stopped ventress). The other characters were well done (clone troopers)in that it helped establish that the Jedi cannot overcome all odds without support. Of course the droids made the episode feel a little kiddish at time (especially the whole argument with them bringing the tanks into the reef). Ventress didn't do much here, but it worked with the storyline (not that she could have done anything against Yoda anyways)
Overall: The story was good, it worked well with Yoda and the connection he had with his troopers. Overall great introduction
