My complaint:
Sit on your couch, open your flyer start turning pages. You’ll immediately be so frustrated with all the pages falling out that you’ll give up, guaranteed. Try it!
Obviously, someone on your team thought it was a good idea to have regular partial pages in it. You should have tested this brain wave out before putting this format into circulation.
Suggested solution:
Have all pages in the flyer the same width so browsing through the flyer will be more enjoyable. Why should reading a flyer be frustrating?
