Russian has two aspects for most verbs: imperfective (process, repeated/ongoing action) and perfective (single, completed action as a result).
смотрели is the past tense of imperfective смотреть.
It presents the action as a process: we were watching / we spent time watching / we watched (neutral statement of what we did).посмотрели is the past tense of perfective посмотреть.
It focuses on the completion or result: we watched it (and finished it / got it over with / ended up having watched it).
In a neutral narrative about what you did yesterday, смотрели is very natural.
If you want to emphasize that you finished watching the film, or that this completed action is somehow important for what follows, you might use посмотрели:
- Вчера мы посмотрели фильм. – We watched the film (from start to finish / and now that’s done).
