"People have gotten into the habit of expecting far too much from those movies, you know-from the first one on, they've been loving recreations of the movie serials that George Lucas must have been hooked on as a kid-the Flash Gordon/Buck Rogers stuff. Nothing expresses that so clearly as titles like "A New Hope" and "The Attack of the Clones," or whatever it is. And then the critics act pissed because they're getting popcorn movies instead of Truffaut."
Going by my previous analogy, a "popcorn movie" is one designed primarily for "entertainment's sake," not an attempt at high art of cinematic technique.
So, one could argue The Matrix would fit the bill, although given all the subtext, it might not.
a great little movie that most no one has heard of that I finally saw on DVD is "the Dish," about one of the satellites in Australia that helped broadcast the moon landing in 1969. No great pretenses, no A level stars (just Sam Neill), but a wonderful small picture.
