I wouldn't skip chapters in a book, and visual novels are like that to me. I can understand not doing every route in F2P mobile games and stuff like that, but I like story-heavy console/PC otome games, so the idea of skipping a whole route in what I play is unthinkable to me. The one time I ran into a route I hated so much that I almost dropped the game entirely, it was for a guy I had thought I would like, and when I stuck through for the rest of the game, the guy I thought was super boring at first glance ended up being one of my most enjoyed. I think it's always good to be open to pleasant surprises like that as well as to get the full story and worldbuilding of what you're reading. Even if I hate a character, I'll still want to do their route so I can hate on them while being properly informed about what I'm hating, and I'll make the experience more enjoyable by complaining to my best friend about what sucks while I play.
