Premise: One guy acts out the entire Star Wars trilogy, including voices, music, and sound effects...plus he adds his own little jokes here and there.
Rating: Great...and an amazingly unique experience.
I can't recommend this for non Star-Wars fans, but if you've seen the movies a bunch, this is a great time. My girlfriend went, and enjoyed it, but I don't think she got all the subtle nuances. However, I went with Guatarrican, who has geeked-out on these movies 1000s of times, like me, and the both of us were laughing so hard we almost peed ourselves. The crowd loved it, too.
The guy who puts it on must have giant, elephant-sized balls, because he stands up there with no props, and makes a total jackass of himself for an hour. Overall, I'm very glad I went, and can honestly say that for $25, I couldn't have found better entertainment.
