Quality is judged by every person individually. Thats why I'm against lists such as AFI's list. I love most of the films there, but having such a list is pointless IMO.
I enjoy True Lies for the cheap humor it has; I like, for example, when Jamie Lee Curtis uses the water in a flowerpot to wet her hair, tryin to be sexy, followed by the funny instructions she gets from the tape- that amuses me, the shallow person that I am.
I also love the witty humor in Casablanca, if that is somewhat of an opposite type of humor in your book. I can watch Casablanca, one of my favorites, on a daily basis (and for a while I did) but I dont limit myself to movies only of that caliber. True Lies is a 'light snickers' type of film, which is another type of films to enjoy. I didnt expect it to be better, in fact, it couldve been a disaster, but I like it the way it is.

I enjoy playing basketball and I enjoy playing chess. I wouldnt call basketball a high-quality game like chess is. I still enjoy playing basketball. Does that help you understand how one can enjoy something that is not of high quality? There are certain degrees of quality.
