For me, safe does not always mean boring. I think De Bachmakov by TdC is the among the most safe scents I've ever smelled, but the stuff is absolutely marvelous. It smells like a perfect spring morning. It's one I look forward to wearing. That being said, I did start a thread about De Bachmakov, asking if it was too nice. If it had a bit more edge to it, it could be a perfect ten for me, but even as is, it's at least a 9. I love it.
On the other hand, there are definitely scents that bore me after a while and I find that I don't reach for them anymore. Just as you said in the original post: "Something that you like but don't love and never reach for.." Bois D'Argent. It's excellent, but for some reason, it's a like, not a love, and I never reach for it. It's been months and I haven't even finished a 2.5ml sample.
