Personally, I don't feel they needed to make this film. The law of sequels is that they have to explain, so the parts of the first film that existed in your imagination are going to be put to rest. That's the only real negative.
The acting was solid. They did a good job of taking disparate horror elements to create something new. And they paid homage to film like The Shinning. They also set up the sequel.
If you like haunted house films, you'll enjoy the first half. If you want to know the specifics of what happened in the first film you'll like the second half. If you like a complicated story line that pays off, you'll like the whole film.
