After hearing all the bad buzz about the sequel, I found it to be pretty entertaining. Even the ending that Ti West hated, felt like it belonged. However, I would really like to know what his actual ending was, because as Gabe said, it's half a movie. It really does feel like there's more, and if there wasn't, it's way too short as is. Even with the hated ending.
This movie would have played in theaters, as it's got enough gross out gore to keep the gorehounds happy, and the black humor is front and center. I'd say it's worth a rental at least. Just to check it out if you're into horror. Just don't expect to see Rider Strong in it for very long.....
