Is it normal to hate time-travel fiction paradoxes?
I really hate time-travel paradoxes. For example, when a character goes back in time and dramatically changes the future. It creates a paradox that makes the plot impossible to occur. If you go back in time and change the future so that an event won't take place, then that event WON'T take place in the future, meaning that the future version of you would have no reason to go back in time and change anything. But then because you don't go back in time, the event WOULD take place, meaning you would HAVE to back in time, and so on and so on.
Another one that I hate just as much is the "meet your future self" paradox (also known as the "scientist's invention" paradox), where a future version of you appears before you and gives you some valuable information that will make you succeed in the future in some way, and then in the future you have to go back in time to tell your past self this information so that your past self will know about it and keep the timeline intact. This means that the "information" would have no original source (you told yourself and learnt it from yourself). It's an impossible situation and it irritates me.
I forgive "Back to the Future" because it's an 80s comedy classic (the first one at least), but it seems that these paradoxes are still being made by people who clearly don't understand why they are completely illogical. I think the best example of a modern film that's infested with paradoxes is "Meet The Robinsons". The way in which the entire storyline is re-written by the end of the film, making it so nothing that occurs earlier in the film can take place, is utterly nonsensical and ruins everything.
So is it normal to be annoyed be these paradoxes? I hate them so much that I could scream. If it's a little kid using them, it's fine because they're young. But it greatly annoys me when a person old enough to understand logic incorporates an impossible time-travel situation into a story or a film, especially the two mentioned above. And it gets even worse with the worst of the worst, the "kill your mother so you were never born" plot. Anyone who writes a story like that without noticing a paradox there needs their head checked.
