I don't really think seeing a video or DVD on the box really counts as actually seeing the film. Just not the real thing. Which means that there's an awful lot of good films I tend to think I've seem, which I turn out not to have, when I think a bit harder and consult my memory.

A film I did see recently (in a cinema) which I really enjoyed was Juno. Not great art, but a good film for all that.
