A little while back, I saw the 2013 remake of 'the Lone Ranger' with Arnie Hammer and Johnny Depp. For those who have not seen it...don't. By all accounts, it is a terrible, horrible film. For me, however, all of the stupid lines, bad acting, and cheesy motivations are forgiven due to a single scene; the 15-minute climax which is a massive train/horse chase/gunbattle all set and choreographed to the William Tell Overture. It is campy and over-the-top, but holy crap is it fun!
I thought it would be interesting to hear any movies (or books, or shows, or games) all of you thought would be irredeemable if not for the presence of a single scene or actor.
