That might be true of some places, but not of this place:
Because this spot always looks exactly like this? Year-round, regardless of time of day or season or weather conditions?
I think it's just a matter of keeping your expectations realistic, and acknowledging that a lot of the pics you are fed by tourism companies and professional photographers have been taken in perfect conditions and then edited until they are an almost hyperbolic representation of that place.
When I research places to travel, I'll actually seek out the best pictures I can find of the place, and hence are probably not "real"; ones that still look good, but show little if any signs of post-processing, so are probably closer to what the place actually looks like; and absolutely terrible pictures, grainy shitty ones taken in far from ideal weather conditions, so you know what you're gonna get if your luck shits on you.
To use Halong Bay as an example:

If you go in having overfed yourself with pictures of the first type, and don't prepare yourself for the possibility that it won't look just like that, unless you luck out and the conditions are absolutely stunning, you're probably not gonna have a good time.
