Yikes, this is a sorely belated review. I had whipped up reviews for all the other Vegas shows I saw during 2010-2011, but somehow Jersey Boys got lost in the shuffle. Oops.
But does it matter? My review is clearly superfluous judging by what other people are saying. This is a fun show! The costumes and stage settings weren't glamorous like The Lion King, but it's hard not to enjoy the story and the music. Jersey Boys is great for most ages (there is some swearing and some suggestive undertones, so may be best to leave the kiddies at the hotel), but definitely perfect for people in their 50's and 60's. The wave of nostalgia this age group experienced while watching was probably how I felt when watching The Lion King. My sister and I were by far the youngest people in the entire theatre and as a result, didn't know all the songs, but everyone else (including my mom!) was singing along and clapping. That honestly was what made the experience totally worth it.
