Took my twins (4.5 yrs) to see this as my boy is going through the Star Wars phase. Perhaps a touch above the heads of 4 years olds and may be better suited for 6yrs+.
Well thought out and executed entertainment themed in the tune of Star Wars pre Anikin went bad as my son states!
For us three and the other six in the theatre yes you read right, nine people showed up! I suspect we all had our kicks from the show.
Classic light sabre and blaster sounds emanate to make you comfortable early on and stretch throughout the show, Jabba is Jabba, 3P0 is 3P0 etc etc, no real surprises.
Go, sit back and enjoy this spin on the classic theme of good v's bad with subtle teacher/pupil nuances - good to see Yoda is in tip top form too.
