At the end?

In the end?

Ambas significan “al final” pero no las podremos usar indistintamente.

• At the end of something: day, class, week, month, film, etc.

At the end of the film, we all went home.

• In the end : al final de “finalmente” (sustiuible for “finally” y “eventually”)

I didn’t like the film at the beginning but in the end I enjoyed it.
