Landry is a great comedian, in my opinion. I went to both of his shows and enjoyed both. I think it would be fine for you to say his comedy is not for you, but to say it’s not suitable for a cruise crowd is really not a fair assessment. Comedy is subjective and you surely aren’t speaking for all cruisers as there was a theatre full of people who really enjoyed the shows. Landry is well established, Norwegian and other cruise lines use him for shows, your comments will not affect his ability to book future shows, but if this was a brand new comedian, a comment like yours could block them in the future. Please consider this in future comments.
