Some backtracking is pretty terrible. For example, I just recently finished playing Tales of Phantasia.
So midway through the game you reach a point where there is a very annoying section of backtracking. You have to spend a night at an inn in a city we'll call City A. There's a cutscene and then you have to go to Harbor A. A ship will take you to Harbor B on a different continent. You then travel to City B and the forest just beyond it. There's another cutscene and you have to go back to City A
but you can't use Harbor B since the trip you took was one way only. So you have to go back through City B, through a mountain pass, walk past City C, walk through City D because you can't walk around it, and reach City E. City E hosts Harbor C which will take you back to Harbor A and thus City A. Somewhere in City A will be a nameless NPC that will tell you to go find a thing in a different forest. So now you have to go to Harbor D on the same continent as City A. This harbor will take you to Harbor E on yet another continent. You walk past City F to another continent accessed by a series of bridges. On the way to your destination you also bypass City G. Past City G is a maze that you are forced to take for the second time to reach the second forest,
the only new area during this segment, to find the important thing. So you finish up finding the thing and a cutscene plays during which you're teleported to the first forest.

Do you see how fucking complicated that is!?! That's bullshit! This is why backtracking in some games,
especially when combined with Fetch Quests, can reach frustrating levels of stupidity, especially when when there's a ton of steps that could be cut out from this convoluted process to streamline it. None of the areas are interesting. None of the areas are changed from when you lasted visited each area. You're mainly fighting lower level enemies between each location that are so incredibly easy to beat that each fight might as well have been skippable.
