To be completely honest, the shadow temple has never scared me once in my life. Numerous horror movies and frightening images I've seen in my days makes the Shadow Temple seem like a joke. The themes are fitting, and the atmosphere feels eerie, yet it's not enough to scare me. I can see why others find it frightening, but it doesn't scare me.
"Scare" and "creep out" are fine distinctions. The Shadow Temple creeps me out, but it doesn't "scare" me. I'm not going to sleep with a light on or anything - but by the same token, I won't be in that dungeon in the dark late at night.
