Of the ones mentioned so far, my least favourite endings are: The Devil Inside and Haute Tension. Didn't like the endings for The Mist or Insidious either, but I mostly hated both those movies anyway so it wasnt much of a let down.
Besides that, pretty much any 'it was all a dream' or 'it was me all along' style endings suck unless they're done really well. A few of my most hated include:
Secret Window
The Number 23
Hide and Seek
