For me it’s Dark Water from 2005 but I think it’s because that movie punished me. I made my family come with me to see this and was relieved of my movie decision making duties for a good five years.
What do y’all think is the worst horror film of all time? Awesomely bad movies like Troll 2, etc don’t count!

The Dark Water remake wasn’t amazing, but it was far from the worse horror movie made, I feel. Horror films that come to mind as the worst I’ve seen (and I’ll try to keep it short) include: Revolt of the Zombies (1936), Blood Bath (1966), Blood Shack (1971), Finis Hominis (1971), The Incredible 2-Headed Transplant (1971), One Minute Before Death (1972), The Thirsty Dead (1974), La tumba de los muertos vivientes (1982), De que estamos hechos (1987), The Brainsucker (1988), The Weekend It Lives (1992), Children of the Living Dead (2001), Reality Check (2002), Jennifer’s Shadow (2004), Cruel World (2005), Death Tunnel (2005), The Curse of El Charro (2005), The Retreat (2005), Hillside Cannibals (2006), Hollywood Kills (2006), Mother’s Day Massacre (2007), Supercroc (2007), Live Animals (2007), O.C. Babes and the Slasher of Zombietown (2007), Freshman Psych (2009), Zombie Women of Satan (2009), Nightmare Alley (2010), and Hellraiser: Revelations (2011). I know that’s quite a list, but every single one is a bottom of the barrel type movie. I can’t just pick one, unfortunately – all are terrible. Hope this finds you well.

Definitely an impressive list, Michael. From the roughly 30% of those that I’ve actually seen, you really are talking some stinkers. I can’t speak to those I haven’t seen (and several I’ve never even heard of), but I’ll take your word that they’re terrible. I think I’ll still need to check them out, though! I stand by my opinion that the 2005 Dark Water belongs here – even if my opinion stems directly from a shameful viewing experience. Perhaps I’ll give it another go in the comfort of my own home. Thanks for taking the time to add an excellent contribution to this conversation. Cheers!
I agree on Hellraiser: Revelations. I hated that movie so much. Another really bad, semi-modern one is Rest Stop (2006).
Rest Stop wasn’t amazing (I’ve seen it two or three times), but the gore, I found, was relatively okay. At least partially memorable (as when the woman is getting her finger bit off). Personally, I think the sequel is worse, but I can understand why Rest Stop would be considered pretty bad. The ending was truthfully atrocious.
