The good news is, this movie was developed as a 3-D project and therefor a lot of planning went into the staging of the shots. According to the director over 90% were shot in 3-D and only some difficult shots were rendered in post production. You can see the passion the filmmakers have with this one and their other movies.
Of course even if you give them the benefit of the doubt, the 3 main characters in this do have quite a few flaws. It might be hard to sympathize with them, but that is up to you. Strange and crazy behavior aside, the movie does have some really scary set pieces (one towards the end, the other reviewer is also referring to). Not a great movie, but a more than decent effort, that might satisfy your horror needs anyway
