The Cable Guy.
And while it isn't a love/hate thing, I have to mention Drag Me To Hell. I find it absolutely hilarious. It's a horror comedy with the werdo style and acting and the downright looney toons scenes...yet, everyone else finds it either crap or legit scary...like what the ef? I love it because I just find it hilarious. Not Cabin in the Woods, or Tuck & Dale vs Evil but still hilarious.
