The Movie/Wings other than Paul

I will be purchasing it, but is it worth it? I've heard a lot from.. pretty much every Wings fan whose seen it that it focuses more on Paul and Linda, and not Wings as a band. How come Paul didn't have any of the surviving members interviewed? I mean, at least Denny Laine. He was the only member to stay with them til the end until basically the Japan incident. I don't think Paul gave him enough credit. The other members that came and went obviously contributed too, so why does Paul make everything about him? I don't mean to sound rude, because I love Paul and Wings are my favorite band.. but you have to admit.. Paul does seem to mix things up a lot, and give himself way too much credit in some places.
