M: Well, did you enjoy it?
W: Yes, I enjoy it much more than I thought I would.
M: Really?
W: Yes, I don’t usually go to science fiction films. I don’t think they are much better than comics on film, if you know what I mean.
M: Yes, sure. And a few years ago, they were certainly like that. (19) But they’ve got a lot better now.
W: Yes, and historical films—that’s what I really like. I never miss a good film set in the Middle Ages. Oh, and love stories—I never miss one on TV.
M: Funnily enough, I don’t like those kinds of films at all. But to come back to this one, I personally didn’t think it was very good. It certainly wasn’t as good as other science fiction films I’ve seen.
W: Wasn’t it?
M: No, not at all. (20) Oh, the effects were very good.
W: (20) Yes, I thought they were marvelous, especially the battle in space, incredible.
M: Yes, but I was going to say I thought the acting was terrible.
W: (21) Yes. I suppose Jason was too good to be true. And what was the name of the baddy?
M: Cargon?
W: Yeah. (21) Cargon was really evil, wasn’t he? But I suppose that’s what these films are all about—good triumphing over evil. And the characters have to be black and white.
M: Well, yes, but not always. War of the Worlds wasn’t like that, for example. Anyway, you enjoyed the film. That’s most important.
W: Yes, I did. Thanks for taking me.
