Go ahead. Buy the tickets. It's a fabulous show. You will have an enjoyable time even if you don't know if you like Jennifer Lopez or are convinced you don't know any of her songs. The amazing set design, energetic choreography and beautiful costumes are worth seeing.
J-Lo's voice is strong and clear and she absolutely owns the stage and it's obvious that she loves what she does and knows what she doing.
The night we went the crowd was very diverse and everyone seemed to have a good time.
So if you are reading reviews and trying to decide what to do, I'll say it again; go ahead, buy the tickets.
