Not necessarily, it depends what the list is about and how the 'lead in' to the list is phrased. Bullet points are a good way to make lists of all types very clear and easy to understand. For example
I like bullet points because:
- they are easier to read than a list that runs along the page
- they can be an attractive design feature
- they increase the 'white space' on a page to improve the overall look
- they force you to think logically about the list's contents
