I wouldn't say that it doesn't get interesting until the third act, but the second can definitely be a bit of a slog because it's largely a retelling of the first playthrough, just from a different perspective. That different perspective adds some context and insights that I appreciated, but I can understand that people that want to get to new content would be annoyed by it.

If you finished the first playthrough and don't feel that anything interesting happened, pushing through to the third probably isn't going to fix that. The third act is new story content, but it revolves around a lot of the same themes and builds on what the first two playthroughs provided, so it's not like you'll be playing a whole new game.
