Neither it was funny nor scary. The attempt to use actor's movie name in punchline failed miserably. It has such a strong cast but the result is complete disaster. It is a perfact example of poor writing.
2 was not excellent but I enjoyed it so went to theater for 3rd movie and regretted it within 15 min. Didn't laugh even once in the 1st half of the movie.
Peole started leaving theater in the 1st half and remaining people started leaving theater even before the movie ended.
Some people stayed till end. Might be like me they wanted to see reaction of other people.
