I "had seen" that movie three times last year. / "Some audiences" thought it was a special effect. I "had seen" that movie three times last year. The last time I saw it, there was an explosion in the cinema. "Some audiences" thought it was a special effect. -Are the three sentences above all correct? In the first quotes, can I say "was" instead of "had been"? In the second quotes, is the usage of "some audienceS" correct? Thank you!
