Help me decide - MJ or Operation Mincemeat

We are coming out for Spring Break for 5 or 6 days and already bought tickets to Stranger Things play - can't wait! We'd like to go to one more show and trying to decide....me, spouse and our 14 year old son. We've been to multiple shows and love it all but we are limited on time. MJ has been on our list for awhile and I've heard really great things about Operation Mincemeat. Help! Thanks!
