I was reading the book Intermediate English Grammar by Raymond Murphy, and I found these two examples in the same unit.
- The film was disappointing. I expected it to be much better.
- The film wasn't as good as we had expected.
I know the difference between simple past and past perfect but these two examples are difficult for me because in the first example it's past tense in both the sentences but in the second example it's simple past and past perfect. How is that possible?
