There are, roughly speaking, three kinds of consistency that a viewer expects from a story:
- External Consistency: Consistency with the real world.
- Genre Consistency: Consistency with other fictional works.
- The fictional universe should behave like other works in its genre, unless specifically noted otherwise. Any fictional concepts, characters, or settings borrowed from other works should behave as they do in those works. For example, a dragon is generally expected to be a flying reptilian creature that breathes fire. If your work takes place in an Expanded Universe, you're generally expected to be consistent with Canon.
- Internal Consistency: Consistency with itself.
- Any rules, events, settings, or characters that have been established within the fictional work continue to exist and function as they did previously, unless otherwise indicated.
- Willing Suspension of Disbelief: Aided by consistency
- Canon: The stuff you're supposed to be consistent with
