I give it a 3.3 so far. Some of the see scenes are a bit under budget, like the little girl running away from 3 grown aliens but seems to get away for awhile. Vader burning Ob wan scene was also a little cheap, Vader turned out the fire previously but couldn't turn it off again and let Ob wan escape. The director needs to add more content to make it believable. Overall, I like the story and it's good to see some of the scenes from the older movies.
Update, the last few episodes are good. I did enjoy the end of the series. I am hoping they bring many more.
