That I can't say, and there would be interesting arguments to be had over quite a few candidates. But I would say that all movies deserve the benefit of being considered as art, such as those benefits might be...

I know that there are films that would fit my own subjective categorization of "not good", but some of those films are also quite popular, which forces me to confront the necessary possibility that I could be missing something. So I couldn't bring myself to say something is aesthetically bad, especially given that "aesthetically" and "bad" are two hard-to-define words crammed right up against each other while trying to describe a third ("art").

I'm not dogmatically leashed to the idea that all movies are art, but I'm sympathetic to the idea.

Jamie, you are pathologically egalitarian!

I'm pretty sure that no one (not even you) would make a case for these three movies as either (a) art, or (b) not bad:

Star Wars Episode One: The Phantom Menace

Daredevil

and the mother of them all: Super Mario Bros. The Movie

Come on. There are clearly some bad movies out there.
