Not brilliant, but not the worst I have ever seen
I think some of the posts on here are unfair, especially people saying that people giving it 8 out of 10 are liars! What's that about?! Maybe some people thought it WAS an 8 out of 10; people are entitled to different opinions you know.
I have seen movies I thought were a 4 out of 10, and they have been an 8 on here, and others that I thought were at least an 8, that are a 5.5 on here. Different people like and enjoy different things. I think Lord of the Rings is boring and long winded, and I would give it a 5 out of 10, but I know some people who think the movie is a solid 10 out of 10. Same with the Godfather; I think it's boring and a 4.5 out of 10 imo. Yet, I know someone who thinks it's the best movie ever, and thinks I am 'stupid' and don't know a good movie when I see it, and I have NO idea what constitutes a good movie. LOL, how arrogant.
The gore in this movie (Pernicious) is good, and the general storyline is OK, the writing and acting is average. But I have seen worse! It's good for a late night scare with your buddies, a few beers, and a Chinese takeaway!
The people who are saying it's crap, then admitting they haven't even seen it make me laugh: yeah, great movie critics.
