What happened:
I watched the story long time ago so I don't really remember.
2.Do you think Johnny English is a good secret agent?Why or why not?
This question is a up to you question but you can say this:
I think Johnny is a good secret agent because he is very clever and funny.He doesn't think about what he is going to do next.(give an example) For example when he is (a place),He...(say what he did) and that makes me think that he is very funny and interesting.
or
I think Johnny is not a good secret agent because he is very silly and always does things the wrong way.(give an example) (name a place the plot) And that makes me think that he is really silly and not clever.
