Good question, hard to pin it down to any one thing, as it is usually a feeling you get when reading the story.
Obvious ‘dead end’ choices for example, are fine in isolation but when they occur too often can get annoying. Basically a “but thou must” in terms of progression.
Others include, scenarios where very specific events combine to push the story in a specific way - It has to be well disguised, if it is too obvious… Also, oversights by the author, for example if they author creates a choice situation and offers say two or three choices that are similar, yet fails to offer a choice that is obvious for the reader. Champions of the Gods did this one or two times, I think the first one choice was a good example; I wanted to obey my parents but that choice wasn’t available, it was either behave petulantly or outright lie.
I found that when writing an epic, because of the scope, I ended up taking certain liberties with the story direction. If I didn’t funnel it in a certain direction then the story would bloat out of control and I’d effectively write multiple stories within the story. I felt, as a writer, that my abilities weren’t good enough to disguise that. When I re-read my work, it just felt off, like I was going through a certain progression path and I felt my audience wouldn’t particularly like that. Unfortunately I couldn’t think of a way to solve that.
Hope that’s useful info.
