I couldn't finish Wild At Heart, though I'm a fan of most of Lynch's films. I couldn't get into the main characters, too uninteresting and unlikable for me to swallow the decadence.
Last movie I finished was Safety Not Guaranteed (small time-travel misteromedy).
It is watchable, with very solid acting, good deadpan humour and not much at stake.
Nice and cozy little flick with one of the best car-following/chase scenes in cinematic history (well, it's more a moment than a full blown scene, but worth watching the movie for).
I bet it's got actual LOL moments when you watch it with friends.
