Is being skeptical bad?

Vicikicca or skeptical doubt, some interpret this as perplexity, is known to be one of the mental hindrances. But why is having doubt bad for one's mind?

For me, doubt is what makes me think more harder to understand certain issues. Doubt leads to creative thinking as well. I am sorry if I have misinterpreted vicikicca but would much appreciate if you could help me out with this
