I subscribe to 'action and reaction' of characters. For example time travel is impossible. Body swaps are impossible. Reliving the same day over and over ad infinitum is impossible. But it hasn't stopped me enjoying these things in fictional works. Like musicals, you can suspend disbelief about people breaking into song and dance and enjoy the movie/stage show.
But throw in unrealistic reactions of characters in these events, and the illusion shatters very quickly. I haven't used time travel or groundhog day plots in my stories, but I have written a body swap story, where a gamer nerd swaps bodies with his bossy twin sister's dim-witted jock boyfriend. The brother is most dismayed by the body swap, and very worried about his sister's amorous advances towards her 'boyfriend'. But if the brother's immediate initial reaction was, 'Oh good, I've swapped bodies with my sister's boyfriend, now I can get into her pants and have my way with her' that isn't realistic at all, and so unbelievable that readers immediately drop out of the story.
