"Serious" movies never have wholly clear endings anymore. Apparently that's what's cool now.
Joke? No great art is fully understandable by anyone but the creator. Most great pieces of literature had unclear or abstract plots or endings, most pieces of visual/physical art have elements unknown to or misunderstood by the audience, most pieces of music have vague lyrics (just as poetry) that inspire more of a feeling than a situation despite having narrative qualities. You can't just rip on it because you don't like not being told what really happened. How many details in life are explained thoroughly to us? Do you know the exact circumstances of your conception? Doubtful. It's doubtful your parents even know, unless it was a very special circumstance.
And Paranormal Activity might be good, assuming that a) your girlfriend won't accuse you of being possessed, b) she won't worry that SHE'S possessed, and c) neither of you have seen it before, because one will ruin it for the other by tensing just before every frightening moment.
