I know this very well that you have watched many timely possession horror movies with a priest who finally comes in after a lot of struggles and saves them. How Holy Terror is different? Yes, i also agree you have watched all the small budget Horror movies with some great content in them. Holy Terror surely falls into that category.
 

Before watching a movie we all look for it's synopsis, when i checked it out, i read this! Believing their deceased son isn't at peace, Molly (Kelly Lynn Reiter) and Tom (Jesse Hlubik) ask a medium (Lisa London) to make contact. But after they invite a vengeful demon to cross over, the couple must enlist the help of a disgraced priest to attempt a dangerous exorcism.
 

The movie begins very slow with lots of explanation which is surely needed for such a plot. But once the film starts the pace, you will surely love what is all happening on the screen. The first Exorcism scene in the movie and the actress Vida Ghaffari is just terrific if you see the film. 
 

If i talk about the performances, i really found Kelly Lynn Reiter a very bad performer in the whole cast. However the film was at some point carried out on her shoulders. But i felt, Kelly's chemistry with other actors was really missing here. Rest of the other actors were really very impressive. Especially i would like re-mention Vida Ghaffari for the second time.
 

The camera work by Gregory Hatanaka was pretty impressive and gelled very well with the entire screenplay. The set design, production value and background score (Especially) was terrific. Rich Mallery brings a fresh feel to the Exorcism screenplay and does good justice as a director of the movie.
 

If you are looking for a possession movie with a different angle, i would certainly recommend Holy Terror which will surely make your day. But please avoid Kelly Lynn Reiter!
