How long is too long for a common route before you get bored?

I don't mind a long common route as long as it's engaging, and it's easy to skip on replays. I know some games try to vary the common route by adding small scene variations, but I don't appreciate it as much because I'm skipping so much and have forgotten the context.

I don't really like a Common Route that is too long, especially if we don't have enough interaction with the LI. But if the common route have small branching or story variation for each LI, it's still bearable lol. I would say, 2-4 hours. More than that, i'd get bored already and losing my focus. Also, a very long common route, and then at the end they just drop us an option to choose which LI route you wanna take, I don't like it the transition just doesn't feel that realistic or smooth for me.
