Bad Movie I Love, the guilty pleasure

Armageddon. It's a bad movie, not even closed to realistic, full of bad overacting, and plot holes galore. But there is something about it that I can just watch it over and over again. I just don't know what it is about it. I even get a bit misty at the end, when Harry stays behind to blow the nuke, and has the touching little goodbye scene with Grace. Then they land, happy reunions, they roil the credits, and A.J. and Grace are getting married, with the picture of Harry watching over them... very emotional. By all formulas that I have to determine if a movie is bad or not, Armageddon should be unwatchable. Who knows, maybe its the little kid in me who wants to go save the world and be a hero.
