Ouch. I couldn't find any, let alone five. I gave a solo vote for Lake Placid 3, just because Colin Ferguson is in it, and I'm a big fan of him from Eureka. But yeah, pretty much everything on that list is abysmal. I even enjoyed Lake Placid 4 more than these, which was basically a teen slasher with a crocodile, but that didn't make the cut.
If the My Super Psycho Sweet 16 movies had made the cut, they'd be easy choices. The first was easily the best (that was 2009 though), but the sequels were still fun.
There was also one called The Truth Below, which was basically a made-for-TV rip-off of Frozen. It wasn't great, but it was better than everything on that list, and it was from the director of Behind The Mask. Might not be considered horror though.
There's also the Chiller TV movies: Remains, Ghoul, Dead Souls, Beneath. None have been great, but they're all still better than the SyFy stuff. Remains has over 1,000 votes, so I'm surprised it didn't make the cut.
