I feel like I want to take superhero franchises gently by the hand and tell them that time travel is never the answer. It's never the answer. Stop mashing reset buttons and undoing character development and avoiding consequences and ignoring all logic and/or timelines and inventing time travel rules only to break them ten minutes later. Just. Just stop. If you have written yourself to a point where time travel is the only answer, you have written badly.

Special mention to the MCU and several DC TV shows. X-men I might give a pass, depending on the mood I'm in.
