Why Do Musicals Like “A Christmas Story” Get Bashed?

Last night FOX aired a live musical production of "A Christmas Story."  My social media feed was full of people saying they shut it off because it was boring, terrible, etc.  Then this morning I heard some more negative comments about it.

I'm not sure if this will help change any minds, but last night's broadcast did not just add songs to the classic movie.  It was a version of the musical "A Christmas Story" that had been on Broadway and at Madison Square Garden and also showed at the Paper Mill Playhouse in Millburn, NJ and in other places around the country.

The songs were actually written by the guys who wrote the music for the Broadway smash "Dear Evan Hansen" and award-winning film "La La Land."

So with impressive writers and performers involved, and a live production that I thought went off without a hitch, my theory is that some people just don't like musicals.  Are you one of them?  Is it the unrealistic nature of breaking out into song out of the blue?  Is it then returning to normal conversation as if the song and dance number didn't just happen?  Please share your thoughts about musicals in general?  And if you have any complaints about or praise for last night's televised musical, please share.
