I'm kind of spacing when it comes to movies, but I'll say that I'm something of a fan of horror movies, both good ones and absolutly cheezy ones. The only ones I usually don't wind up liking are SLOW horror movies where not much happens.
I could point fingers to things like my enduring fandom of things like the "Nightmare On Elm Street" series or "Phantasm" but for all the criticisms leveled at them these are series that went on for multiple installments, and made tons of money and enduring film legacies. I don't know if you can call any of them objectively bad looking at the overall legacy.
I guess to throw out some random stuff the movies "Blood Gnome", "Death Of A Ghost Hunter", and "Behind The Mask, The Leslie Vernon Story" to all be quite entertaining when I watched them on Netflix, and I don't think any of them could be considered good by any objective standard, nor do they have an enduring prescence to lend doubts to their status as relative failures. Those I all watched on Netflix and should put some perspectives on the kinds of bad horror movies I've enjoyed.
In the long term I suppose "Prince Of Darkness" and "Ghosts Of Mars" both by John Carpenter being a couple of my favorite 'B' horror movies of all time count. The former, "Prince Of Darkness" is one I feel should get a LOT more recognition than it's received, and be considered more of a cult classic. I guess I'm wierd seeing as I liked that one a lot more than "The Thing". "Ghosts Of Mars" is pure cheese, combining sci-fi action, and the combined tropes of zombies and possessing ghosts into one picture, it features Natasha Henstrige, Ice T, and Jason Statham fairly early in his career. Sometimes I can't believe that someone actually made that movie, and what's more that I feel like I'm the only 'B' movie fan who has ever seen it.
