how to get what answers i want

Howdy

Basically im wanting to ask a question to get the information that
will inform me of narrative change and atm i can only think of;

"what do you think was going on in this film?" or " what do you
thinkthe main characters motiv / reason for doing / stance on
... etc?"

which would show change in narative if the answers varied in the
other films :D its pretty general and wide enough to make the
viewer react and say exactly what they thought was going on in
the scenes in the film.

Also I need to think of a lead, Colin Cartiwright describes it
as the type of questionaire that "makes" the subject answer no
until they come across a question that they will likely say yes
to because they feel they have answered no for so many qestions
:) which might tie into the second question variety :D.

I need to avoid the question

"what do you think of this film?" which is too general and will
therefore get a basic answer - which was a result from my last
years test and I would have the results if Abertay wuld let me
have my research back :S

have a great day
