The Bold and the Beautiful often does a Christmas themed episode at the end of which the cast directly address the audience and wish them a merry Christmas. Although this can be a thoughtful sentiment, it can also detract from the fictional storyworld of the show by drawing attention to its constructedness.
Do any of the shows you watch do this? Do you like it or not and why?
If it is a comedy or a show that breaks the fourth wall on a regular basis, then no. If it is a drama or something like that, then I wouldn't like it. I think I have only seen it happen in a few comedies anyway.
