Definitely depends. It can vary even within a single site.
For example, a page that is utilized within schools for educational purposes will likely have a high bounce rate. Students visit the page, get their information, and then back out of the website.
Another page, might be getting a more generic term from search engines. The visitor then instead visits many pages either looking for information or for a product to buy.
What's more important, is you should ask the question, "Should this page lead to clicks to other pages or is this page enough for my visitors?"
Obviously, the answer will vary differently between pages. If it's the homepage or a category page, you'll definitely want a very low bounce rate. However, if it's an inner page, such as a widget review, you'll most likely have a high bounce rate.
