This was released today, and as much as I enjoyed the first two parodies, this one fell really flat. The animation is really beautiful and the character designs are all great; but the jokes are way more "miss" than "hit".
I don't regret buying it, but I don't think they put a whole lot of effort into the writing for this one.
I just got it for my birthday yesterday from the wife. I really enjoyed it probably due for my love for Jedi. The opening crawl with them going off on Fox for pretty much forcing to do the trilogy sets the tone to lower expectations. I thought they could do more at Jabba's Palace, but then I thought they zoomed through Cloud City in Empire. The Seth Green vs. Seth MacFarlane had a nice payoff. I did like the cameos from American Dad and the Cleveland show. They just just do a show with Mort, Klaus and Rollo. The special features were pretty nice too.
The good: It's the same game. Nothing has changed. The "new" set is just a freshened up version of the same set. The music and overall presentation haven't changed at all. As for Carey...he's got some work to do.
