Going into this movie, I was sure that it's gonna below average. But didn't really think that it would suck so terribly. I was going along with the below average material I have been shown on screen. There are two twists. One comes towards the end of the movie which was unexpected. We'll come back to that later. The other one was that I was thinking it to be a rip off of "The Ring" (2002) but it revealed itself to be a rip off of "I Know What You Did Last Summer" (1997). That's a "great" twist, man. Even there's a cheesy and cringe-worthy line acknowledging it. From the start, I was sure that it would be just a ghost haunting down story rather than a real horror with terrifying stuffs. I got that. It was what I expected and wasn't a disappointment. It has a some clichéd horror plot devices used in the most obviously convenient way. Also, there's a forced and equally clichéd romance of a horror movie. Also, the movie about a nun. Okay, I understand why she's all after killing her murderers. But why was the character so insane? Since the movie about the nun, wouldn't it be better if you establish the character with much more depth than what we saw? Apart from this it takes "anything can happen in a horror movie because it's a horror movie" thing a little too seriously. I mean, every single major plot point is appears at the crucial moment without any build-up. Finally, the ending. Before this, whatever that was going on wasn't so interesting but it was making sense in whatever the hell it was. The final twist ruins a movie which was barely holding up. You show that the nun and Eve were some kind of split personality? I mean what was with all those watering stuff before all those people died? And when Eve's mother was killed by the nun, who was Eve herself, then how were her fingerprints not found? So, it wasn't enough to rip off one movie, you try to make it "Fight Club" (1999) in the end? This is one of those epic and totally unexpected twists which completely ruins a movie. On the whole, it was a nonsensical movie and was a waste time. It gets an "E" and a "1.7/10".

I am a huge horror fan, particularly Spanish horror. This film had so many possibilities to be good. It's a marvelous idea, a vigilante ghost nun, as most of what has come out of Jaume Balangueró's mind. Both visual and sound effects were also pretty good. But everything was shamefully spoiled by bad direction, awful casting and a painfully bad (exposition, exposition!) script. Too bad. Maybe Balangueró should write and direct himself a remake...Moreover, I don't really understand why this had to be spoken in English by actors who can't really speak English (and when they do, they do it so bad it just makes their performances even more fake). If you look at contemporary Spanish horror films like El Orfanato or Rec, the performances are totally in tune with this type of stylish ghost story - and that is being realistic, being believable as someone like ourselves, like real people, because that is the only way horror achieves it's goal. Unfortunately, everything failed in La Monja.

The only good thing of this movie is its final twist. In 97 minutes of film we can only save one single idea, which was totally wasted in this movie I must say! For more than 90 minutes this film is just a collection of clichés, bad acting, stupid ideas and disclosures, complete lack of suspense, stupid deaths, terrible special effects; all this in a pathetic and unoriginal plot… until the last three minutes, where, FINALLY, a good idea appeared! It's nothing outstanding or an extremely original idea, but, at least was a "decent" good idea, the only one the entire movie has! I won't spoil it, but I must say I think that idea with a better plot, better FX and, definitely, a better acting, would turn into a good film. If you watch this movie and can stand it until the end you will know what it is

I don't usually like to comment on the acting in a movie, because it is the one thing that people who have agenda against a film will go after. In this movie, I will make an exception. The acting in this film are below average all around. I mean halfway into the film, I wonder how the hell did the producer and/or the director gets around casting such an ensemble of people who can't act. Even-though the production value was good, the ill written story just compounded on top of the bad performance of the actors, and there is even a half-hearted attempts to a twist to the ending of the movie, which ends up quite confusing. Is all the Spanish horror films this disappointing?
