the cover letter is informative, motivating participation in the study, and contains the most important parts of a cover letter (except for the researcher's name and last name). in your cover letter, you mention people who have seen got, but not those who have also read the books, so the question "do you think that the game of thrones tv show did a good job adapting the series?" will not generate accurate results. other than that, this was a good attempt to create an internet survey!
good questions, and i enjoyed the sense of humor present in some of them.
love your topic. interesting questions. i like your questionnaire.
