[General media] What media has the most plausible "masquerade"?

By masquerade I mean that the fictional world is just like the real world, except that there is an ancient secret magical society/race/whatever living apart from normal humans that cover up their existence from most of humanity in some way, and most normal humans outright refuse to believe anything that isn't normal. Harry Potter is probably the most famous example, but it's a common trope in urban fantasy. 

Often, the masquerade feels forced, you question why the masquerade even exists in the first place if magic has always been around, and the way it's kept over the years starts to strain credibility since even if most people would be skeptical about aliens or the supernatural, they would still notice weird stuff.

Have you ever seen a masquerade that made perfect sense to you in why and how they've managed to stay hidden for so long?

*Heroes* is a pretty good take on this:

- Powered individuals are extremely rare, and seem to appear in bursts, so you'll have long stretches where the majority of them have all died off, and their existence can't be verified.
- Previous generations of powered individuals were all born before modern recording equipment. 
- The previous generation has a powerful organization devoted to enforcing the masquerade full time.
- An event at the beginning of the series vastly increases the quantity of powered individuals that exist, and the masquerade cracks after only a few years.  It was clearly going to crack eventually, so that does end up happening.
